Homemade Macaroni and Cheese

This came from Dave's mom, very good.

Cook 1 and 3/4 cup macaroni ( I use whole wheat)

White Sauce : melt 6 TLBS butter and add 6 TLBS of flour to make a paste.
Add 3 cups of milk and stir and bring this mixture to a full boil. (add salt and pepper to taste)

Drain macaroni and place half of it in a casserole dish. Slice extra sharp white cheddar cheese on top of the macaroni and top with half the white sauce mixture. (carefully mix through)

Top with the remaining macaroni, cheese and then the rest of the white sauce.

Bake at 350 for 45 min (covered) Remove cover and bake an additional 10 or 15 min.
