Basic No-Pectin Berry Jam Recipe

Step 1

Rinse berries. Hull and halve strawberries (if using).

Step 2

Place a small ceramic plate in the freezer.

Step 3

Combine the prepped berries, sugar, lemon juice and salt in a large heavy-bottom saucepan. Mix well, then use a fork or potato masher to mash slightly. Let sit 20 minutes, stirring occasionally, until the fruit has started to release its natural juices.

Step 4

Place saucepan over medium heat and bring up to a boil, stirring frequently, until the fruit has broken down and the mixture has reduced and thickened, about 20 minutes.

Step 5

Test the jam for doneness by placing a small spoonful of jam onto the frozen plate and tilting the plate. If the jam thickens and holds, it's ready. If it still remains thin and runs, allow the jam to cook an additional 5 minutes or until it reaches your preferred texture.

Step 6

Once ready, transfer into sterilized Mason jar(s) and cool to room temperature. Seal and store in refrigerator or freezer. Once open, use jam within 2 weeks.
