I am hoping to make two 3 quart casserole dishes worth of macaroni and cheese. The recipe I have calls for using two pounds of pasta, but doesn't indicate the volume of food that it will yield after cooking down, or after combining with sauce.
Assuming I will use either small shells or fusilli (haven't bought the pasta yet because I don't know how much I will need), how do i translate poundage of pasta to volume?
