Method:
Preheat oven to 375 degrees. Bring a large pot of salted water to the boil and add macaroni. Boil until "al dente" and strain in a sieve with running cold water (this will stop the macaroni from continuing to cook and getting too soft). Grease an ovenproof baking dish. Prepare a white sauce by melting about 2-3 tablespoons butter in a saucepan, adding 2 tablespoons flour until the mixture forms into a ball (do not let it get brown). Now quickly add alternatively, evaporated milk and prepared stock until it forms a smooth white sauce. Add a little salt and white pepper to taste and the grated cheese (the amount of cheese varies to your taste). Put macaroni into the prepared baking dish, pour white sauce over it and top with more grated cheese. Bake in pre-heated oven for about 40 mins, or until light brown on top.
