Pomona's Universal is a low methoxyl type pectin extracted from citrus peel. Its jelling power is activated by calcium (included), not by sugar content.
Pomona's Universal Pectin makes thick jam and jelly with rich, full flavor undiluted by large amounts of added sugar. Ordinary fruit pectin require your jam or jelly to be 55-85% sugar to set firmly.
Ingredients: 1 packet low methoxy citrus pectin and 1 packet monocalcium phosphate.
