Fresh cranberries are in season only from October to December-but don’t despair. They freeze beautifully! Cranberries keep well in the refrigerator for about a month, and can be frozen for about 9 months. (Just long enough for the next crop to come out)
Don't wash cranberries before you freeze them, and don’t bother thawing them when they're going in baked goods-you can use them straight out of the freezer. This super food is as convenient as it is good for you!
