STEAK AND POTATO PIE

From 1922:

Cut the steak in small dice; put in a saucepan with a little chopped onion, salt and pepper to taste, four potatoes cut in slices, and enough water to cover. Stew for 1 ½ hours. Then put in a pie dish till cold. Have ready two cups of boiled and mashed potatoes, mixed smoothly with a tablespoonful of melted butter. Put this over the top of the meat in a thick layer. Sprinkle some breadcrumbs over and put in a hot oven till the potato is quite brown.
