Macaroni 3 Cheese Recipe

Place penne in boiling water and cook until al dente.
Slice tomatoes thinly and sprinkle with salt and sugar and allow to stand.
Sauce: Melt butter, add cornflour, stir for about 3-4 minutes. Add milk a little at a time, add cheese. Stir to get a smooth consistency. Add nutmeg, white pepper and cayenne and stir into the sauce.
Mix the penne and sauce together and pour into the dish.
Place the tomato slices on top with a sprinkling of breadcrumbs, black pepper and extra cheddar cheese.
Bake in a very hot oven or under the grill, long enough to brown the top and warm the tomatoes.
