Pineapple Jam... EASY Tropically Exotic - Small Batch Canning This really is VERY VERY EASY to make. The canning process is simple, Pineapple and limes provide plenty of acid to keep the finished jam from spoiling for months. It is also the basic recipe you can use to make almost any fruit jam you could think of... Strawberry, Grape, Blue, Black or whatever Berry works just as well as the Pineapple. And it is deliciously sweet, and a little Tropically exotic!
