Cheese and leek macaroni cheese

Mealtimes wouldn't be mealtimes in this household without a sneer. I've added a leek to tonight's macaroni cheese which is sure to attract some curled lips and unfavourable comments. It will also give your mac 'n' cheese a bit of colour and a touch of sweetness.

I used wholemeal pasta for extra sneers

Cheese and leek macaroni cheese

2oz butter
1½ oz plain flour
About 15 fl oz milk (I used skimmed)
1 leek
8oz pasta
7oz grated cheese
¼ teaspoon English mustard

Cook the pasta. While you're doing that, put the leeks and butter into a pan over a low heat. Cook for about 5 minutes (still low) after the butter has melted, then add the flour and stir well. Pour in the milk, a bit at a time, stirring continuously. When the milk's all in add the cheese, mustard and a few grinds of black pepper and stir some more. Drain and rinse the pasta, and mix it into the sauce. Transfer to an ovenproof dish, sprinkle over another couple of ounces of cheese and stick under a hot grill until the cheese is melted and bubbling.
