Enjoy!
From my darling Aunt Toby:
Heat oven to 375.
Nuke 1/2 of a cube of butter
Add 1/4 cup of flour right into the measuring cup with the butter
Add 2 cups of milk.
Nuke and stir until thick. Check often, it will boil over.
Cook 8 oz of macaroni. [I use 12 oz. of whatever pasta I have on hand.]
Slice.
Layer macaroni, cheese, etc.
Top with white sauce.
Bake until brown on top. (About 35 minutes)
Easy and 1,000 per bite!
