Proper roux, baked
40 minutes · serves 4 · Medium
What you need
- 400g macaroni
- 50g butter
- 50g flour
- 600ml milk
- 250g strong cheddar, grated
- 1 tsp mustard powder
- Breadcrumbs
What you do
- 1Boil the pasta two minutes short of the packet time. It cooks again later.
- 2Melt butter, stir in flour, cook 2 minutes — it should smell biscuity, not raw.
- 3Add milk a splash at a time, whisking, until you have a smooth pourable sauce.
- 4Off the heat, stir in most of the cheese and the mustard powder. Season hard; pasta dulls it.
- 5Fold through the pasta, top with the rest of the cheese and breadcrumbs, bake 20 minutes at 200C.
