how to put cherries in the freezer
Some cooks prefer to freeze separated cherries on a cookie sheet and then pack in bags for freezing. To freeze sour cherries for pie filling, stir 3/4 cup of sugar into each quart of pitted, whole sour cherries. Pack in rigid airtight containers with 1/2-inch headspace or airtight bags. Frozen cherries will last ten to twelve months in the freezer.
