Gammon & onion marmalade mac ‘n’ cheese

Preheat the oven to 220ºC, gas mark 7. Bring a large pan of salted water to the boil. Add the macaroni and simmer for 6 minutes, until al dente. Drain then return to the pan.

Meanwhile, put the butter in a medium pan over a medium heat. Melt and add the flour and mustard powder, then season and cook for 2 minutes, stirring. Pour in the milk, a little at a time, stirring until smooth before adding more. You should end up with a smooth, creamy sauce and may not need all the milk.

Stir 2/3 of the cheese into the sauce, until melted. Pour it into the pan with macaroni, add the gammon or ham and mix until the pasta is coated.

Tip into a large, deep ovenproof dish (about 2L) and spread evenly. Dot with the onion marmalade, then scatter over the remaining cheese. Bake for 35-40 minutes, until bubbling and golden on top.
