Traditional Northumberland Pan Haggerty

Thinly slice potatoes and onions.

Melt butter or lard in a heavy-based frying pan.

Layer the potatoes and onions in the pan, seasoning each layer well with salt and black pepper.

Cook over low heat with a lid on for about 20-30 minutes until the potatoes are tender.

Remove the lid and sprinkle a generous amount of grated mature cheddar cheese over the top.

Place the pan under a hot grill (broiler) until the cheese is bubbling and golden brown.

Serve directly from the pan.
