Harvested from bogs when cold weather arrives and available throughout the winter months, tart, fresh cranberries are a signature fresh fruit of autumn and early winter. They are packaged in 12-oz. plastic bags that contain 3 cups of berries. Cranberries can be enjoyed throughout the year by freezing them in airtight freezer bags; they keep up to 1 year in perfect condition. The combination of tart cranberries sweetened with oranges, another fruit of winter, is one of the classic flavor pairings in baking.
