Slowly pour in the ginger ale, stopping to stir if needed. Pour the ginger ale down the side of the glass to prevent too much foam.
Add ice. Decorate with a fresh berry if you like. Enjoy!
To make the puree...Fill the blender canister with fresh berries. If they are sweet and juicy already, just puree. Or, add sugar or sugar substitute to taste. If the berries are not very juicy, you can add a bit of water or even orange juice to help them blend up.
