Jam is a bit of chemistry. So this recipe has no weights, as it’s not exact. You usually use equal weights of fruit as you do preserve sugar but that can vary on pectin content of fruit and the temperature of the mixture. What I will say is this: as long as you keep stirring, and do not allow the jam to burn, it can be saved. If it gets too thick add some water, if it is too runny reheat it and boil it for a bit more.
For this recipe I used Strawberries and blackberries.
HOME COOK conserves strawberry (this is a bit of a cheat)
A knob of butter
Firstly place a side plate in the fridge you’ll need it later. To start with you soak your fruit in salted water over night if like me you collected it from the wild as opposed to store bought. If you bought your fruit from the store give it a rise. Then remove any leaves from the strawberries or twiggy bits left on the berries. While doing this quarter the strawberries. Add them to the pan and set on a medium light. You don’t need to be gentle you want them to mainly break up.
The fruit juice will start to be released from the fruit and it will smell delicious. Keep constantly stirring the mixture as it can be at rise of the fruit sticking. Here you can add the HOME COOK conserve strawberry. It is a bit of a cheat because you can use this to make jam without any of the fun of cutting up fruit but I use it does bulk up the quantity and it helps get the consistency right. I bought the tin I used at Lakeland.
Yeah my mim helped :)
Here you can turn up the temperature on you stove as the liquid helps the jam from sticking. You then add the preserve sugar; add the same weight as fruit you used. Keep stirring.
Bring the Jam up to a rolling boil. Keep stirring. You want a constant boil that does not slow when stirred. Here add a knob of butter to reduce the foamy scum.
Here turn off the heat, put your oven on to a medium heat and boil the kettle. Pour boiled water into jars; I used kilner jars and recycled other jam jars. Then to dry the jars out place them in the preheated oven upside down and leave for five minutes.
During this five-minute turn the heat back on under the jam and bring it back up to a rolling boil. Stirring CONSTANTLY and despite the fact it smells like heaven do not even think of dipping your finger in it. You will feel the burn of a thousand suns.
Take your plate out the fridge and drip some of the jam onto the plate. If after thirty seconds if the jam is solidish to the touch, consistent with jam, then its time to pot up. Take your jars out the oven using oven mitts and place them on a heat resistant surface. The either using a jug or a funnel and lifting the pan, pour the jam into the jars leaving as little space as you can.
Once the pan is empty and cooled slightly use a lump of bread to wipe as much of the jam off as you can, you get a taste of your jam early and it makes the pan easier to clean. Once the jam in the jars has cooled enough that it has started to solidify place a parchment ring on top of the jam, this helps create surface tension allowing the jam to set more evenly and reduce any air left in the mixture which might make it go bad. Leave until totally cooled before sealing the jars, as you don’t want to trap condensation in the jar as this increases the likelihood of bacteria growth. Then you are done.
