I'm looking at recipe number 3 and the ingredients have me a bit confused. On the top, I see two cups uncooked macaroni and on the bottom I see two cups cooked macaroni. Is this the same macaroni just cooked vs uncooked, or do I need 4 cups total, half cooked? How is it then used in the recipe? I only see instructions to boil macaroni, so what happens with the already cooked macaroni?
