To freeze strawberries, wash, dry and hull the berries. Spread the berries on a cookie sheet lined with parchment paper or some other non-stick surface. Place in the refrigerator until chilled through (45 minutes to 1 hour.) Then place chilled berries in the freezer until the berries are frozen solid. Once they are frozen solid they can be placed in a zip-top bag or other air-tight container for easier storage. Frozen berries make a great addition to fruit smoothies and other quick and healthy snacks. You can also use this method to freeze blueberries, blackberries and raspberries, to name a few.
