For a smoother jam, you can strain the mixture through a fine-mesh sieve after cooking to remove the seeds. Adjust the amount of sugar to your liking, depending on the sweetness of the blackberries. Sterilize your jars properly if you plan to store the jam for an extended period. The jam will thicken more as it cools, so don't overcook it. To test the consistency, place a small spoonful on a chilled plate; if it sets up quickly, it's ready.

Apr 30, 2024I found that 15 minutes was perfect for my jam to set. Be sure to do the cold plate test!
