It must be washed in several waters, after having been well picked; then put a quarter of a sieve of spinach to a gallon of water and three ounces of salt, boil for ten minutes till tender, drain on sieve, press a little with your hands to extract part of the water, chop it up fine, put in a stewpan, with a quarter of a pound of butter, a teaspoonful of salt, half ditto of pepper, put on a fire with a drop of warm broth for a few minutes, and serve.
