Home economics; Macaroni and cheese

Last week we made Maccaroni and cheese we made a roux sauce (white sauce) containing butter, cornflour, and milk, the reason we used cornflour is to make it a smoother sauce. We cooked the pasta with boiling salted water. I think overall we did a good enough job of gathering the ingredients together, but it took a bit of extra time. But the end result turned out good it tastes awesome but not as good as homemade macaroni and cheese.
