I have just been informed by a nothern friend lancashire hot pot should actually be made with chunks of lamb and prater pie should be made with minced beef.
PRATER PIE
1lb good-quality lean mince beef (as little fat as possible)
2 onions, peeled and chopped.
2 carrots, peeled and chopped.
4 large potatoes, peeled and cut into irregular slices.
2 teaspoons Bisto powder made up with a teacup of cold water (or proper stock if you have it).
salt and pepper.
FOR THE PASTRY
6oz plain flour
3oz lard (or half marge, half lard)
Pinch of salt
Cold water to bind
METHOD
Layer approx one third of the potato slices on the bottom of a casserole dish, scatter approx one half of the onion and carrot over this, then crumble approx one half of the mince by hand over them to form a third layer. Season with salt and pepper.
Repeat layering and seasoning, ending with a layer of potatoes.
Pour the Bisto/stock over the casserole. Add water or more stock as necessary to bring the level of liquid at the bottom of the casserole up to one inch in depth at most. It is important not to drown it by having too much liquid in the casserole to start with.
Cook in oven at Gas Mark 5 for 30 minutes. While it is cooking, make up the pastry in the usual way by rubbing the fat into the flour and binding with cold water.
After the 30 minutes, remove the casserole. Roll out the pastry to the correct size and place on top of the pie in the casserole dish. Make it fit roughly at the edges, folding the edges over on themselves if necessary. The pastry lid should sit on top of the potato and meat, not over the rim of the casserole dish.
Make a couple of slits in the pastry lid to allow steam to escape. Return the casserole dish to the oven (leaving off its glass lid so that the pastry will cook properly.
Allow to cook for another 20-25 minutes until the pastry lid is a very pale golden brown.
Serve with simple greens and pickled red cabbage.
