I picked the last of the rhubarb just in time to make two batches of strawberry and rhubarb time, something I have been whining about for a long time of getting round to doing. It tasted pretty good and a great way of padding out your strawberries to make enough jam if you are lacking. It is like a burnt pink colour when it is done and looks lovely in the jars. I used fresh rhubarb picked straight from the patch and strawberries I had defrosted from the freezer, gradually adding to them over the weeks to build up enough for 100g worth.
When using jam jars, if you are planning to keep them for yourself, you can use any jar you like from a shop bought produce. If you are planning to sell them, you need to purchase some unlabeled jars without any slogans on them – it would not do to sell homemade jam in a Bonne Maman jar so keep those lovely ones for yourself. Also, I would recommend investing in some wax discs to put over the surface of the bottled jam before you put the lid on to prevent it from moulding quickly. Lots of jam that I made last year, perfectly well and sterilised, has still grown a little mould on top whenever I now open it. It is slightly unappetising.
On that charming note, here is the recipe:
Strawberry and Rhubarb Jam
(Makes about 4 370g jars worth)
– 500g rhubarb – 500g strawberries – 500g granulated sugar – Juice of 1-3 lemons – 1/2 bottle of 250g Certo Apple Pectin (or another form of pectin)
- Cut the rhubarb into pieces, about 2cm big, to help it break down quickly and so that you do not have large chunks of rhubarb balancing on your toast. Put it in a large pan with the strawberries. Turn the heat up high and bring to the boil, stirring to prevent burning.
- Add the lemon juice and sugar, stirring them in.
- Bring the entire mixture to a furious boil, stirring occasionally. Allow it to boil for probably about ten minutes, until the mixture is thickening.
- Meanwhile, put a china plate inside a freezer to use for testing the pectin later on. When you are ready, put a small dollop of the jam onto the china plate a put it back in the freezer for a minute or two. Take it out and run your finger through the middle of the jam – if the mixture wrinkles, it has enough pectin in it. If it does not, continue to boil the mixture and check again continuously.
- When ready, turn the heat off and stir in 1/2 bottle of liquid pectin of choice to make sure that it is set. Allow the mixture to cool completely before bottling and placing a cool, dry, dark place overnight to allow it to set.
- To sterilise jam jars, preheat the oven to 150C and put the jars and lids inside for about five minutes until they are hot to the touch. Using oven gloves, remove from the oven and leave them to cool completely before using.
