How do you know when jam is ready with a thermometer?
If you are using a jam thermometer, then you can test it once the temperature reaches 105 degrees. To test the jam for its setting point, remove the saucepan from the heat and spoon a little jam onto a cold refrigerated plate and leave for a few seconds – it should wrinkle softly when you push your finger through it.
Follow this simple 6-step blackberry jam recipe for a delicious fruit preserve that makes for the perfect piece de resistance at breakfast time!
Put the blackberries, lemon zest and lemon juice into a large saucepan and cook over a low heat. Stir gently until the blackberries are soft and plenty of juice has been released.
TOP TIP
Unopened, this jam should be keep in a cool, dark place for up to least 6 months.
Press gently with a masher to release even more juice and break up some of the fruit, but don’t reduce all the blackberries to pulp.
TOP TIP
Once opened, be sure to store your blackberry jam in the fridge.
Put a couple of small plates in the freezer ready for testing the setting of the jam.
TOP TIP
Feel free to adjust the amount of sugar in this recipe to suit your preferences, just remember that this will affect how your jam sets and how long it takes to get to its setting point.
Add the Tate & Lyle Jam Sugar then stir gently until it dissolves completely. This is important to prevent the jam from crystallising during storage.
Meanwhile, sterilize 7 x 200ml jars by washing them in hot soapy water, rinsing well, then place them in a low oven at 150°C/Fan 130°C/Gas Mark 2 for 15 minutes.
Increase the heat steadily to a rolling boil. After 10 minutes you can test to see if the setting point is ready.
