Ham and mushroom lasagne

If you haven't bought ready-made béchamel sauce, melt the 85g butter in a saucepan and add 3tbsp plain flour. Cook for a few mins, then gradually add the hot semi-skimmed milk, whisking all the time until smooth and thickened. Season with salt and freshly ground black pepper and a grating of fresh nutmeg.

Soak the dried porcini in 300ml (½ pt) hot water for around 30 mins, then strain into a bowl. You can use the soaking liquid for a casserole or a soup. Melt the knob of butter in a large frying pan, then sauté the chestnut mushrooms with some seasoning until tender. Cut the Parma ham into large strips.

Preheat oven to 180°C (350°F, gas mark 4). To assemble the lasagne, put a layer of the porcini and chestnut mushrooms in the ovenproof dish, then some Parma ham strips, then some sheets of pasta. Spoon over some béchamel and a handful of Parmesan. Continue layering and end with pasta, béchamel and Parmesan.

Bake for 40 mins or until browned and bubbling. Serve with a green salad.
