This is my Mom's recipe. I make it all the time:
Mac and Cheese
1 and 1/2 cup macaroni (I use elbows)
6 Tblsp butter
1/4 cup flour
1/2 tsp dry mustard
1 tsp salt
1/4 tsp pepper
3/4 tsp Worcester sauce
3 cups milk
1 tsp instant minced onion (or you can use fresh onion, chopped very fine)
3 cups shredded sharp cheddar cheese (the sharper the better, in my opinion)
3/4 cup soft bread crumbs
Cook macaroni and put to the side. Melt 4 Tblsp butter. Blend in Flour and seasonings and stir until smooth. Add milk and onion. Cook until thickened, stirring constantly. Add cheese and stir until melted. Mix with the cooked macaroni. Put in 2.5 Qt casserole. Top with crumbs mixed with remaining butter, melted. Bake 375˚ about 40 min.
Personally, I always leave off the bread crumbs on top - never liked my mac and cheese that way, but I guess it's the traditional method.
Yum! :)
