MAKING JAMS, JELLIES & FRUIT PRESERVES (B2909)

Process all jams and jellies in a boiling water canner for a safe, high quality product. University of Wisconsin-Extension does not recommend sealing jars with paraffin, or inverting sealed jars as a final step.

Freezer jams and jellies take about half the time to prepare as cooked jams and jellies. The resulting product is less firm, but has more fresh fruit taste.

Plastic freezer containers with tight-fitting lids work well for storing freezer jams and jellies. Be sure to leave enough space at the top of the container for expansion during freezing.
