Transfer the hot jam to sterilized, clean jars while it's hot for short-term storage. Allow it to cool completely before sealing it with a lid. Store the jam in the refrigerator. It can last in the refrigerator for up to one month if left unopened. Once opened, consume within 7-10 days. If freezing, consume within one year for best results. Be sure to leave enough room for expansion in the Mason jars or freezer bags before placing them in the freezer.
