I have always made a white/cheese sauce or gravy with flour salt, white pepper and margarine. What a fantastic idea!! I mixed this and then put in small compartment ice trays and froze. Wrapped on the counter once or twice, popped right out and then I put in freezer bags. I might add this is also a wonderful base to thicken soups especially bisque soups. Thanks so much for posting.
These are a great time saver or recipe saver! I made up a batch and pull one out of the fridge if I need to thicken something or to start a white sauce. Really good idea. Thanks Bunlady!
