Wash all fruit before freezing. Strawberries, blueberries, blackberries and raspberries can be frozen whole.Do not remove the hulls of the strawberries before washing to prevent the fruit from absorbing water.
Allow the berries to drain and dry completely. To prevent the berries from getting crushed spread them out in a single layer on papers towels.You can very gently pat them with paper towels if you are in a hurry but air drying completely works the best.
Remove the hulls from the strawberries before the next step.Place the berries on a cookies sheet in a single layer making sure none of the berries are touching. Freeze for one hour until the berries are firm to the touch.
