Microwaving Creative Gourmet frozen berries and fruits See Defrosting Creative Gourmet frozen berries and fruits to find out how to defrost berries and fruit in the microwave. Place frozen berries and fruit in a shallow microwave-safe dish, ensuring that the fruit is even and level in the dish and not piled high (about 2 cm in depth is ideal). Sprinkle with caster or icing sugar or a sweetener to taste (if microwaving cranberries add the sugar after the cranberries are cooked and tender). Gently toss to combine. Cover and microwave on high in 2 minute bursts until tender and juicy. Stand for 5 minutes before using or placing in an airtight container to store in the fridge.
