Potatoes a l’Américaine :—Cut up four good-sized boiled potatoes into thick slices : flavour half a pint of milk with onion, spice, pepper, and salt, as for bread sauce; strain and thicken it, as laid down for melted butter, with butter and flour, till you have a nice sauce blanche; place your slices of potato in this, and heat them up to boiling-point: take the saucepan off the fire, stir in the yolk of an egg, add a large spoonlul of chopped parsley, with a pat of butter the size of a shilling, and serve.
