I don't use any measurements. I just cook the macaroni until it is tender and layer in a buttered pan. Put a layer in the pan and put colby or cheddar cheese on it and butter and salt and pepper. Put another layer of macaroni on that and end up with cheese and butter and salt and pepper on top. Add some milk about 1/4 to 1/2 way up the macaroni. Bake in a 350 degree oven until milk absorbs.
