Mix butter and flour, pouring boiling water over, boil up, add salt, and half of onion and parsley; pour into oiled baking dish, put peanuts in, sprinkle remainder of onion and parsley over, cool to lukewarm, lay crust on, let rise, bake.
A pastry, rice or mashed potato crust (without eggs) may be used ; if pastry, put a cup in the center of the pie to support the crust ; with potato crust it would be better to simmer the onion in the oil of the sauce first.
Bake or boil peanuts (leaving quite dry when done) with sliced onion and a little carrot, browned flour and a little tomato, parsley, salt and celery salt, a trifle of thyme and garlic if desired. Thicken slightly, turn into baking dish, cover with mashed turnip, sprinkle with crumbs and chopped parsley, dot with butter or oil. Bake until top is nicely browned.
