- STEP 1
Put a saucepan with the water onto boil, and then add all the macaroni.
- STEP 2
Leave the macaroni to simmer for as long as the pasta bag says to (Usually around 12 minutes) but do not cook thoroughly as this will happen when baked.
- STEP 3
Get a smaller saucepan and mix the butter and flour until combined and dough like (do this on a low heat) and then slowly add the milk, a little at a time.
- STEP 4
When all the milk is mixed in, add the mustard powder and slowly add the cheese, a handful at a time. You will know when the sauce is done because it will have thickened. Add as much seasoning as you want.
- STEP 5
Drain the pasta and put the sauce on top. Add a little grated cheese and bake for around 7 minutes on high heat (around 180 degrees or gas mark 6/7) until the cheese on top has melted and gone golden.
