Melt a heaping tablespoonful of butter in a spider and when it bubbles
stir into it a heaping tablespoonful of flour, cook until it turns a
dark brown, taking care not to let it burn, add to it enough
well-seasoned vegetable stock to make the sauce the proper consistency,
then pour it into a granite-ware saucepan and add one small cucumber
pickle, two olives and a few capers, all chopped very fine; season with
salt and pepper to taste.
