Take two onions and cut them into small dice, fry them in a stew-pan with some butter; shake the pan well for a few minutes, add five heads of celery, two handfuls of spinach, two cabbage-lettuces cut small, and some parsley. Shake the pan again, put in two quarts of water, some crusts of bread, a teaspoonful of pepper, and a blade or two of mace. Let this boil gently for an hour.
