50g bread cut into small chunks
2 tbsp butter , plus 1 tbsp melted
350g spiral or other short pasta
1 garlic clove, finely chopped
1 tsp English mustard powder
3 tbsp plain flour
500ml whole milk

Spread 50g bread chunks over a baking sheet, drizzle with 1 tbsp melted butter and season. Bake for 6 mins until crisp, then set aside.
Boil 350g spiral or short pasta for 2 mins less than stated on the pack, then drain. Meanwhile, melt 2 tbsp butter in a saucepan.
Add 1 clove finely chopped garlic and 1 tsp English mustard powder, cook for 1 min, then stir in 3 tbsp plain flour. Cook for 1 min more, then gradually whisk in 500ml whole milk until you have a lump-free sauce. Simmer for 5 mins, whisking all the time until thickened. Take off the heat, then stir in 250g grated mature cheddar and 25g grated parmesan.
