LEEKS AU GRATIN

Preparation Method :

• Remove most of the top green leaves from the leeks. Wash thoroughly under running water, then drain.
• Place the leeks in a saucepan of boiling salted water and cook for 15 to 20 minutes until tender, depending on thickness.
• Drain, reserving the cooking liquid, and put the leeks into a flameproof serving dish. Keep hot.
• Melt the margarine in a saucepan and stir in the flour. Cook for 2 minutes, stirring.
• Gradually add the milk and enough leek cooking liquid to make a medium thick sauce.
• Add the nutmeg and cheese and stir until melted. Add salt and pepper to taste.
• Pour the cheese sauce over the leeks in the dish.
• Mix the remaining cheese with the breadcrumbs and sprinkle over the top.
• Place under a preheated hot grill for a few minutes until the top is golden brown.
