Homemade jam is usually so full of sugar, but it doesn't have to be! Using Pomona's Pectin, one can make a low-sugar, honey-sweetened, or fruit juice-sweetened homemade jam. This particular pectin comes from citrus peel. The jelling is activated by calcium water (mono calcium phosphate) which comes with the pectin. It is so easy to make jam from all of your freshly picked fruit of the season. Making and canning jam is one of the great ways to preserve the harvest!
