Look for fresh blueberries that are firm, dry, plump and smooth-skinned and relatively free from leaves and stems. Berries should be deep purple-blue to blue-black; reddish berries aren’t ripe, but may be used in cooking.

My mother-in-law and I dreamed up this jam after we'd been picking blueberries one day. She wondered if blueberries, raspberries and strawberries would taste good together. So she made a test batch—and we quickly learned that they definitely did! Then I came up with my own version of the jam. I preserve everything from our garden! —Karen Maerkle, Baltic, Connecticut
