Watching my grandmother can hundreds of jars of tomatoes, peaches and pears inspired me to first try making jams and jellies myself. This jam is one my family enjoys on warm homemade corn or blueberry muffins. The cinnamon's a bit of a surprise. —Barbara Burns, Phillipsburg, New Jersey
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
For a big berry taste, you can't beat this tasty spread. With a flavorful foursome of blackberries, blueberries, raspberries and strawberries, this lovely jam brightens any breakfast. —Marie St. Thomas, Sterling, Massachusetts
After one taste of this delightfully sweet and simple jam, people will find it hard to believe that you didn't spend many long hours in a hot kitchen. Of course, you don't have to let them in on your "secret"!
