Place penne into boiling water and allow to cook until al dente.

Slice the tomatoes very thinly and sprinkle with salt and sugar and allow to stand.

To make the sauce add butter to a saucepan and once melted add the cornflour, stir for about 3-4 minutes. Then add the milk a little at a time, then the cheese. Keep stirring to get a smooth consistency. Finally add the nutmeg, white pepper and cayenne and stir into the sauce.

Rub garlic on the inside of a baking dish (optional).

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 more cheddar cheese.

Bake in a very hot oven or under the grill, long enough to brown the top and warm the tomatoes.
