Sauce Robart for Rumps or Steaks
Put into a saucepan a piece of butter the size of an egg: set it over the fire, and when browning, throw in a handful of sliced onions cut small: fry them brown, but do not let them burn: add half a spoonful of flour, shake the onions in it, give another fry, then put four spoonfuls of gravy, pepper, and salt, and boil gently ten minutes. Skim off the fat: add a teaspoonful of made mustard, a spoonful of vinegar, and half a lemon juice: boil, and pour round the steaks, which should be of a fine yellow brown, and garnished with fried parsley and lemon.
