The one, the only, original recipe I have ever made up.
1 tbsp olive oil
2 leeks, cleaned and sliced
4oz (110g) smoked back bacon, rinded and chopped
small can or jar of black pitted olives
8oz (220g) pasta
2oz (55g) cheddar cheese
1oz (30g) mozzarella cheese (or you can just put 3oz (85g) cheddar or mozzarella if you prefer)
for the roux:
1 1/2 oz (40g) butter
1 oz (30g) flour
3/4 pt (15ml) milk
salt and pepper to taste
Pre-heat the oven to gas mark 4 (180C, 350F).
Put on a large pan of water and bring it to the boil. Cook the pasta for a little over 10 minutes until it’s just cooked. Drain and keep warm.
While that’s cooking, heat the olive oil in a frying pan and fry the leeks and bacon gently for about 10 minutes until soft.
To make the roux, melt the butter in a small saucepan and then stir in the flour, mixing thoroughly until it’s smoothly blended. Then over a low heat, gradually add the milk a little at a time, stirring continuously so that you don’t get any lumps. Wait until it thickens up again before adding any more milk. When all the milk is in, keep stirring until it just starts to bubble: by this stage it shouldn’t be too thick, about the consistency of double cream (if it’s too thick, add more milk). Add some salt and a grind or two of pepper to taste.
Combine the pasta and the leek and bacon mixture in a baking dish, and slice the olives into it. Then pour over the roux, stir well and season to taste. Grate the cheese over the top, pop it in the oven and bake for about half an hour or until the cheese is brown and bubbling. Serve with a green salad or leafy veg.
