A while back I purchased a bag of frozen blueberies and one of strawberries, and they are just sitting in my freezer. What can I do with them -- aside from making a sauce or smoothies, neither of which is of interest? I am thinking of some sort of baked goods, such as muffins or a coffee cake. Can they be substituted for fresh berries in a reciped? My concern is that there will be a greater volume of liquid that will affect the recipe. Ideas?
