A delightfully savoury tart which perfectly marries leek with rich gruyere flavours.
1 rectangular piece of ready rolled puff pastry
25g (1oz) butter
450g (1lb) leeks, thinly sliced and washed
Salt & black pepper
1 clove of garlic, crushed
300ml (0.5 pint) double cream
115g (4oz) Gruyere cheese, grated
1. Line the baking tray with the puff pastry. Melt the butter in a saucepan; add the leeks, salt, pepper and garlic. Cook until soft for about 10 minutes, then cool.
2. Beat the cream with the eggs, nutmeg and three-quarters of the cheese. Place the leeks in a flan case and pour over the egg mixture. Sprinkle the remaining cheese over the top.
3. Cook on the floor of the Roasting Oven for about 25 minutes until golden.
