Yes! Freeze berries with sugar if your berries were slightly under-ripe or if you plan on using them in jams or pies. To use the dry sugar method, sprinkle 1/2 cup of sugar per quart of strawberries after you’ve washed and cut your berries. Once you’ve coated the berries with sugar, transfer them to the airtight container. There’s no need to do the pre-freeze step since the sugar will help keep the berries together during the freeze cycle.
