FSM 348: Is it Safe to Double the Recipe When Making and Preserving Jams and Jellies?

Transcript [Music] It’s food preservation season. Welcome to Food Safety in a Minute. Making jam and jelly, a family tradition, for others a way to reduce food waste, and a fantastic way to preserve extra fruit. Is it OK to double the recipe of jams and jellies as you preserve them? The National Center for Home Food Preservation recommends against doubling recipes of jams and jellies. Testing shows doubling “can disrupt the balance of ingredients, potentially preventing the batch from setting properly.” It also “increases the cooking time, which may result in undesirable textures or burning of the jam or jelly.” It may even lead to uneven cooking before processing, increasing food safety risks. Always use a tested recipe from the National Center for Home Food Preservation or Washington State University. From Washington State University Extension, this is Susie Craig.
