This delicious, small batch Easy Seedless Blackberry Jam is made with just 3 ingredients, blackberries, granulated sugar and freshly squeezed lemon juice and no pectin.
Before you start:
Place 2 - 3 saucers/small plates in the freezer.
Sterilise jars by washing in hot soapy water (or take straight from dishwasher), fill with boiling water, empty and then place in oven for 20 minutes at 140°C where you leave them until the jam is ready. Washed lids should be sterilised with boiling water and then left to drain (if still wet place in oven once you’ve turned the heat off and run with just the fan for a few minutes).
