SPINACH SAUCE
Put 1 cup of freshly cooked or canned spinach, from which the juice has been pressed, into a basin or mortar, and chop or mash to a pulp. Melt 1 tablespoon of butter in a saucepan, add to it 1 small onion chopped fine, let cook slowly for five minutes, then add the spinach, and let cook for ten minutes more. Put 1 cup of milk into a double boiler with 1 bay leaf, 1 stalk of celery (or some celery seed), and when it boils add 1 tablespoon of flour blended with 1 tablespoon of butter; season with salt and pepper, and when thickened stir the spinach into this, sprinkle with grated nutmeg, and let cook together for ten minutes. Press through a sieve before serving.
