Sauce Piquante
Two or three thin slices of Spanish onion fried lightly in a little good beef dripping. Two large tablespoonfuls of bovril added to the onion which must be allowed to adhere lightly to the pan. Half a teacup of hot water and a tablespoonful of best malt vinegar. Let the whole come to a boil and thicken slightly with a little carefully mixed flour and water. Strain and serve in a sauce boat.
