Am going to cook macaroni cheese as I am hungover, I haven't had it for about a million years and I AM GOING ON A DIET TOMORROW 
I plan to use 2 oz butter, 2oz flour, english mustard, cheese (mature cheddar), salt and pepper. I also have some mascarpone in the fridge, some mushrooms and some smoked bacon.
Anyoe have any hints about what would make the most delicious macaroni before I eat cardboard til christmas?
Thank you!
