Onion

The onion (Allium cepa L., from Latin cepa “onion”), the most widely cultivated vegetable of the genus Allium. Its close relatives include the garlic, shallot, leek, chive and Chinese onion. The word onion comes from the Latin word ‘unio’ meaning unity, because it grows as a single bulb.

The onion is most frequently a biennial or a perennial plant but is usually treated as an annual and harvested in its first growing season. Onions are cultivated and used around the world. As a food item, they are usually served cooked, as a vegetable or part of a prepared savoury dish, but can also be eaten raw or used to make pickles or chutneys.

The onion plant has a fan of hollow green leaves and its bulb at the base of the plant begins to swell when a certain day-length is reached. The bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale (leaves) that envelop a central bud at the tip of the stem. In the autumn (or in spring, in the case of overwintering onions), the foliage dies down and the outer layers of the bulb become dry and brittle. The crop is harvested and dried and the onions are ready for use or storage.

The geographic origin of the onion is uncertain because the wild onion is extinct and ancient records of using onions span all over Asia. The first cultivated onions are the subject of much debate, but the two regions that many archaeologists, botanists, and food historians point to are central Asia or Persia. They were probably almost simultaneously domesticated by peoples all over the globe, as there are species of the onion found the world over. Food uses of onions date back thousands of years in China, Egypt and Persia. Traces of onions recovered from Bronze Age settlements in China suggest onions were used as far back as 5000 BC, not only for their flavour, but the bulb’s durability in storage and transport. Ancient Egyptians revered the onion bulb, viewing its spherical shape and concentric rings as symbols of eternal life. Onions were used in Egyptian burials, as evidenced by onion traces found in the eye sockets of Ramessess IV. The fourth book of the Hebrew Bible composed around the 5th century BC mentions onions when recounting scarce foodstuffs available: 11:5 — We remember the fish which we used to eat free in Egypt, the cucumbers, the melons, the leeks, the onions, and the garlic. In the 6th century BCE, the Charake Samhita, one of the primary works in the Ayurvedic tradition, documents the onion’s use as a medicinal plant, a ‘diuretic, good for digestion, the heart, the eyes, and the joints’. Pliny the Elder wrote about the use of onions and cabbage in Pompeii. He documented Roman beliefs about the onion’s ability to improve ocular ailments, aid in sleep, and heal everything from oral sores and toothaches to dog bites, lumbago and dysentery. Archaeologists unearthing Pompeii long after its 79 CE volcanic burial have found gardens resembling those in Pliny’s detailed narratives where the onions would have been grown. Onions were taken to North America by the first European settlers only to discover the plant readily available, and in wide use in Native American cooking. According to diaries kept by certain of the first English colonists, the bulb onion was one of the first crops planted by the Pilgrims.

Shallots are a type of onion, but  was formerly classified as a separate species, A. ascalonicum. Like garlic, shallots are formed in clusters of offsets with a head composed of multiple cloves. The skin colour of shallots can vary from golden brown to gray to rose red, and their off-white flesh is usually tinged with green or magenta. You can use shallots in the place of onions when cooking, but they do make smaller harvests.

In the gardening world, we are used to three different colours of onions. We grow the brown/yellow/golden, the red/purple and then the white, which I must admit, I have never tried. Across the world the brown is often used in everyday cooking, the red is often served raw as it is sweeter, and the white are often used in Mexican styled cuisine as they are very sweet once sautéed.

IMG_1604.jpg

Here are some varieties to try:

Brown: Radar (one of my favourites), Alisa Craig, Stuttgarter, Centurion, Hercules, Sturon, Hytech

Red: Red Baron, Electric (another favourite)

White: Snowball

Shallot: Griselle (good), Jermor, Bistro, Golden Gourmet, Picasso, Mikor, Yellow Moon, Vigarmor

Onions are best cultivated in fertile soils that are well-drained. Sandy loams are good as they are low in sulphur, while clayey soils usually have a high sulphur content and produce pungent bulbs. Onions require a high level of nutrients in the soil. Phosphorous is often present in sufficient quantities, but may be applied before planting because of its low level of availability in cold soils. Nitrogen and potash can be applied at regular intervals during the growing season, the last application of nitrogen being at least four weeks before harvesting. Or try planting them in your crop rotation after the runner beans. Bulbing onions are day-length sensitive; their bulbs begin growing only after the number of daylight hours has surpassed some minimal quantity. Most traditional European onions produce bulbs only after 14 hours or more of daylight. Southern European and North African varieties are often known as “intermediate-day” types, requiring only 12–13 hours of daylight to stimulate bulb formation. “Short-day” onions, which have been developed in more recent times, are planted in mild-winter areas in the autumn and form bulbs in the early spring, and require only 11–12 hours of daylight to stimulate bulb formation. Onions are a cool-weather crop. Hot temperatures or other stressful conditions cause them to bolt, meaning that a flower stem begins to grow.

IMG_2481.jpg

Onions may be grown from seeds or from sets. We often use sets (I’ve tried shallot seeds and grown a total of two miniature shallots that were the size of my pinkie’s fingernail…) Onion seeds are short-lived and fresh seeds germinate better. The seeds are sown thinly in shallow drills, thinning the plants in stages. In suitable climates, certain cultivars can be sown in late summer and autumn to overwinter in the ground and produce early crops the following year. Onion sets are produced by sowing seed thickly in early summer in poor soil and the small bulbs produced are harvested in the autumn. These bulbs are planted the following spring and grow into mature bulbs later in the year. Certain cultivars are used for this purpose and these may not have such good storage characteristics as those grown directly from seed.

If growing from seed, sow 1cm (½in) deep in rows 20cm (8in) apart from late February through to early April. Thin by removing weaker seedlings, first to 5cm (2in) apart and then later to 10cm (4in) apart. Plant spring sets March – April and harvest August – September. Plant winter sets in September and harvest May – June. Plant onion sets 10cm (4in) apart in rows 30cm (12in) apart. Gently push the sets into soft, well-worked soil so that the tip is just showing, and firm the soil around them.

IMG_1594.JPG

Routine care during the growing season involves keeping the rows free of competing weeds, especially when the plants are young. The plants are shallow-rooted and do not need a great deal of water when established. Bulbing usually takes place after 12 to 18 weeks. The bulbs can be gathered when needed to eat fresh, but if they will be kept in storage, they should be harvested after the leaves have died back naturally. In dry weather, they can be left on the surface of the soil for a few days to dry out properly, then they can be placed in nets, roped into strings, or laid in layers in shallow boxes. They should be stored in a well-ventilated, cool place such as a shed.

Freshly cut onions often cause a stinging sensation in the eyes of people nearby, and often uncontrollable tears. This is caused by the release of a volatile gas, syn-propanethial-S-oxide, which stimulates nerves in the eye creating a stinging sensation. This gas is produced by a chain of reactions which serve as a defence mechanism. Chopping an onion causes damage to cells which releases enzymes called alliinases, generating sulfenic acids. Lacrimal glands produce tears to dilute and flush out the irritant.

Onions are rich in carbohydrates, sugar, soluble and insoluble fiber, sodium. They are a very good source of vitamin C and so good for building your immunity. They are also a good source of enzyme-activating manganese and molybdenum as well as heart-healthy vitamin B6, fiber, folate, and potassium. Onions are surprisingly high in flavenoids, one of the top ten vegetables with Quercetin content. If you want to retain the flavonoid, peel off only the outer dry skin as the outer layers are more concentrated with flavenoids. Onions have been found to have anti-inflammatory properties and help in problems like rheumatoid arthritis or allergic airway inflammation. Studies show that onions help balance blood sugar levels. Onions also have anti bacterial properties. There are many stories and folklore. It is supposed to have saved families from plague and other infections. The anti bacterial effects of the onions act against the streptococcus mutants that cause various dental cavities and gum diseases. Studies suggest that the consumption of onions enhances the anti clotting capacity of blood. Onions have been known to increase bone density, reducing the risk of fractures. The sulphur content in onions is excellent for the connective tissues as well.

Natural treatments that use onion:

-Onions are also used in the treatment of piles or haemorrhoids. The juice of 30g of onion mixed with water and sugar is administered to the patient twice a day.

-In alopecia (hair loss), a topical application of onion juice has been said to initiate the re-growth of hair.

Cough, cold and asthma is often treated with a serving of onions, as it is known to decrease bronchial spasms. Onion juice mixed with honey helps cure bronchitis and influenza.

-Onions are also known to stimulate the growth of good bacteria while suppressing the growth of harmful bacteria in the colon, reducing the risk of colon cancer.

-The juice of Tulsi leaves (holy basil) with equal quantities of lemon juice and onion extract applied on the skin takes care of many skin diseases.

-A slice of cut onion rubbed over acne is supposed to clear up the skin quickly by taking off the bacterial infections.

-Naturopaths recommend eating onion and jaggery to increase body weight.

-Eating one raw onion a day reduces cholesterol in the blood.

-A remedy for warts is the application of the juice of one finely chopped onion sprinkled with salt and left for a few hours. This needs to be repeated 3 to 4 times a day until the wart dries up.

-The cure for cholera in Indian households is one onion pounded with 7 black peppers. It lessens vomiting and diarrhoea immediately. A little sugar could be added to the mixture to increase its effectiveness.

-A tea made of onions boiled in water, cooled, strained, and given to patients suffering from urinary infections gives immediate relief.

-Slice an onion and rub it over the sting of a bee, wasp or a mosquito to ease the discomfort.

-In the treatment for chicken pox, Indian women would serve the afflicted person a bowl of curd rice with chopped onions.

 

Onions can be added to anything. They are the base of all sauces, add flavour to a salad when served raw, and are just fundamental in the kitchen for pizza toppings, curries, stir fries, pies…

Butternut Squash and Chickpea Tagine recipe

IMG_7346.jpg

We’ve had some sad looking butternut squashes staring at us in the kitchen for a while and I finally took pity and tried out making my own quick tagine-styled dish. It is really good and not at all hard so give it a go if you have a squash glowering at you from the fridge!

IMG_7349.jpg

Butternut Squash and Chickpea Tagine 

Serves 6

-1 small butternut squash/ 1/2 a large one -1 onion, finely sliced -Olive oil, for frying in -1 garlic clove, finely diced -16 cherry tomatoes or 4 large tomatoes, sliced -450g cooked chickpeas -Rice, to serve -Greens, to serve

  1. Cut up the butternut squash and remove the peel. Cut into fine chunks and fry in the olive oil with the onion, continually stirring so that the squash cooks, but does not burn. Fry for about 5-10 minutes, or until the squash is browning slightly and is cooked through.
  2. Add the diced garlic followed by the tomatoes. On a high heat, stir the mixture like you did when frying the squash. You want the tomatoes to start to break down and release their juices, but not to burn. This could take between another 5-10 minutes.
  3. Add the chickpeas and mix in well.
  4. Serve with rice and greens. Also lovely with sweet potato.

IMG_7120.JPG

Pepper Pasta

(Serves 2)

-2 servings spoons of pasta -Olive oil -1 red, 1 yellow and 1 green bell peppers -2 handfuls of cheddar cheese, grated

  1. Bring a large pan of water to the boil. Add the pasta and then leave it to simmer for about ten minutes, or until the pasta has cooked. Drain and set aside.
  2. Add a generous splash of olive oil to a frying pan.
  3. De-stalk, de-seed and slice the three peppers into long, thin strips. Scrape  them into the frying pan and bring to a high heat, stirring. Once they start to char slightly, turn down to a simmer.
  4. Scrape the pasta into the frying pan and mix into the peppers. Bring the heat up briefly for a minute or two and then remove the frying pan from the flame.
  5. Divide the mixture in half and serve onto two plates. Sprinkle a handful of cheddar cheese over the top of each helping. Serve.

Recipe: Poached Egg with Broccoli

We’ve just been picking our (lately planted) Calabrese broccoli this week.

IMG_6726.JPG

So in the spirit of the good old green, some people’s worst enemy, but a delicious green flower to me, here is a little easy-peasy recipe to try at home.

It might sound like a strange combination – but really, eggs are surprisingly good with broccoli. I urge you to give it a try.

IMG_6728.JPG

Poached Egg with Broccoli

(Serves 1)

-1 egg -1 medium sized broccoli -Salt and pepper, to season (optional) -A slice of bread or some potatoes (optional)

  1. Bring two small pans of water to the boil. In one pan, add in the broccoli once you have cut the florets up into small pieces. Peel of the outside of the stem and cut into matchsticks and those are delicious boiled too. Reduce to simmer for about 10 minutes. Drain.
  2. Meanwhile, crack the egg into the other boiling pan of water. Leave to boil for about 2 minutes, or until the egg white looks cooked. Remove from the heat. You can use a poached egg pan instead – in that case, grease one of the egg cups with butter and crack the egg into it and leave it to cook that way. This works better with eggs that are not very fresh than the first technique.
  3. Spoon the egg and the broccoli out onto a plate. Add a sprinkling of salt and pepper, optional, and serve with some bread or some cold potatoes, optional again. This can make a nice, light lunch, or a starter to a fancy dinner party.

Sweetcorn

IMG_1552.jpg

Sweetcorn (Zea mays convar. saccharata var. rugosa), is a variety of maize with a high sugar content. It is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and mature (dent stage), sweetcorn is picked when immature (milk stage) and prepared and eaten as a vegetable, rather than a grain.

IMG_1655.jpg
Ready for pollinating

The cultivation of corn as maize began over 8000 years ago in Mesoamerica, a geographical area which includes central and southern Mexico, and Central America. Corn was first domesticated from teosinte (Zea mexicana), an annual grass native to this region. Wild teosinte mostly has value as a fodder plant, as it provides very little edible seeds. The first archaeological evidence of domesticated corn comes from the San Marcos cave in Tehuacan and the Guilá Naquitz cave in the state of Oaxaca, Mexico. The corn in San Marcos cave is dated to over 5,000 years ago. The cobs from the Guilá Naquitz cave were dated to over 6200 years old. Humans first domesticated corn by selecting the teosinte plants that had the largest amount of edible seeds until they eventually provided a substantial food source. In the process, humans have transformed corn into a plant that can no longer self-sow and modern corn now requires breaking the tightly bound cob to remove the seeds. Wild teosinte, however, is very fragile and the seeds easily fall off and grow new plants. Without human interaction modern corn would probably cease to exist.

IMG_1657.jpg
Tassels – this is where the grainy seeds need to fall to pollinate

The Iroquois, Native American tribes, gave the first recorded sweetcorn, called ‘Papoon’, to European settlers in 1779. It soon became a popular food in southern and central regions of the US. Open pollinated cultivators of white sweetcorn started to become widely available in the US in the 19th century. Two of the most enduring cultivars, still available today, are ‘Country Gentleman’and ‘Stowell’s Evergreen’. Sweetcorn production in the 20th century was influenced by the following key developments: hybridisation allowed for more uniform maturity, improved quality and disease resistance, and, in 1933 ‘Golden Cross Bantam’ was released. It is significant for being the first successful single-cross hybrid and the first specifically developed for disease resistance. Open pollinated (non-hybrid) corn has largely been replaced in the commercial market by sweeter, earlier hybrids, which also have the advantage of maintaining their sweet flavour longer.

IMG_1658.jpg
Grainy seed tops

There are different varieties of sweetcorn – old types and supersweet types as well as mini types. Choose only one variety or they cross pollinate and make a gross hybrid that you don’t want.

I’ve only grown ‘Swift F1’ – and it is brilliant.

IMG_8576
5’3+ tall sweetcorn, 2018

Sow in pots as early as March or as late as May, indoors. I use tall yoghurt pots filled with compost. Keep them in warm temperatures to grow with plenty of water and sunlight. Plant them out when they are about 7cm tall and the frosts have most definitely passed, May or June, 30cm apart. Sweetcorn is wind pollinated so plant them in clustered groups (picture the fields of corn grown on the country farms around Britain, all packed together) rather than rows to maximise pollination. Plant in soil that has been prepared with compost and well-rotted manure. I keep feeding mine with Blood, Fish and Bone and well-rotted manure or a liquid feed throughout the season to encourage the growth of the corn itself. Keep well watered in any dry periods. To increase pollination, try brushing the dusty pollen off the tops of the sweetcorn onto the tassels – this is where the corn will grow if pollinated. The tassels on the plant will turn yellow if fertilised. The cobs are ready when the tassels turn dark brown, July-September. To check, peel back the green covering and pierce a thumbnail into one of the niblets – if the liquid that is released is milky, your sweetcorn is ready. If it is clear, leave if a little longer but check daily.

IMG_3545.JPG
Undeveloped corn on the cobs 

IMG_8698

The aim is to harvest sweetcorn in its prime. The sugars convert to starches rapidly once the corn leaves the plant and the taste will only become poorer as time goes on – same for asparagus and peas. Have the pan of boiling water ready, pick and plunge your cobs straight in. Or freeze them immediately (it stops the sugar/starch conversion process).

IMG_3216.jpg
Tassels dying back – the corn is forming

The only problems with sweetcorn are they take up space, they might not pollinate as reliably as insect pollinated plants (it will be very weather dependent) and if you have a problem with mice you might need to consider some protection.

IMG_8689

For companion planting, consider the ‘Three Sisters’ from the USA: sweetcorn, beans and pumpkins. My first year I grew pumpkins with the sweetcorn. Last year I grew lettuces and radishes between them. This year I am considering a variety of cucurbits because they both enjoy the sunny conditions – courgettes, pumpkins and squashes, that is.

IMG_8702

To cook and eat sweetcorn: it can of course become ‘corn on the cob’ – boil, grill or barbecue and slather in butter and hand them out for people to chew off the little gold nuggets. To remove the kernels from the cob, boil for a few minutes in boiling water (don’t add salt, it hardens the kernels), get a sharp knife and scrape them off into a bowl and serve.

IMG_8704 They are lovely with any meal that includes boiled veg, salads, mixed with tuna and mayonnaise is a traditional one, delicious with peas and baked potatoes mashed with butter, they are a traditional vegetarian option for the barbecue – try spreading some chill sauce over the top after grilling for a spicy taste. I think they are delicious also in a stir fry and a great addition to Egg Drop Soup with Vegetable Stock. I offer you the other recipe that springs to mind when I picture sweetcorn – my mum’s sweetcorn fritters.

IMG_2724.JPG

Sweetcorn Fritters 

(Makes enough to serve 4 people a few each)

-260g fresh sweetcorn (if you are using bought canned, use a 325g tin) -100g gram flour (or plain flour, gram flour is made from chickpeas and adds extra protein) -3 eggs -120g cheddar cheese -80g Gruye cheese -50g grated courgette or 1tbsp milk, optional -Small knob of butter, for frying

  1. Scald the fresh sweetcorn so the corn comes off the cob easier. If you are using tinned sweetcorn, drain it and set to one side.
  2. In a large bowl, sieve in the flour. Make a well in the middle. Add the eggs and stir them into the flour to make a batter.
  3. Grate the cheese and mix it in. Ass the corn and either a little courgette or milk to make it a dropping consistency, only a little though.
  4. Warm up the butter in a frying pan and drop spoonfuls of the batter into it – four per frying pan. Fry on one side and then flip over, using a spatula, and fry on the other side. Press down on the batter – when it is no longer leaking liquid, it is cooked through. Place on a plate lined with kitchen roll. Serve with vegetables, salad, rice, potatoes, dips… ketchup?

Recipe: Stewed Plums

My mum is very into her stewed plums at the moment since I made plum crumble this year. Fortunate as we have so many Victorias (no greengages 😦 ) that I don’t know what to do with them all. I have no space in the freezer to keep them for jam and no time to make jam!!!

She begged me one evening for more stewed plums on their own without the crumble. It was really quick, easy and got rid of a container full of them. Great!

She loved eating them just plain but she also had some with yoghurt. Custard would be delicious with it. It only takes about ten minutes and makes a really quick and simple dessert or snack.

Stewed Plums

-400g plums -1-2 handfuls of granulated sugar

  1. Remove the stones from the plums by cutting them in halves. Place in a non-stick pan over a high flame.
  2. Add the sugar and stir into the plums. Allow the plums to heat up and start bubbling before turning down the flame down to a low heat. Continue to stir to encourage the plums to break up.
  3. Leave simmering for at least 10-15 minutes. Remove from the heat and serve plain or with yoghurt, ice cream, cream, custard or with pieces of shortbread or plain sponge cake. Store left overs in an airtight container in the fridge or freeze.
