Put a tablespoonful of butter into a frying-pan, and stir until it is
brown—_not_ burned. Add a half-teacupful of boiling water in which has
been stirred a tablespoonful of browned flour previously wet with cold
water. Add salt, a teaspoonful Worcestershire sauce or anchovy, the
juice of a lemon, and let it boil up well. Pour over the steaks when
you have arranged them in the dish.
