Getting a good set for strawberry jam can be hard without extra pectin, lots of sugar, or a long cooking time. Enter the cranberry. Lots of natural pectin, beautiful ruby red color, and a little tartness make this the perfect strawberry jam.
Shaped like a gooseberry, dark like a currant, the Jostaberry is a hybrid of the two. Halfway between its parents in sweetness,it has tons of pectin so no added pectin is required. Cooks up quick too. From Balsam Farms, East Hampton
