1/3 cupful dried crumbled Irish moss, covered with cold water and allowed to soak 15 minutes. Pour off water, pick over the moss, add a quart of milk, cook in a double-boiler for no more than 30 minutes. Add a pinch of salt and strain. Add 2 tsp vanilla, 1/4 cup sugar, strain again, pour into individual molds dipped in cold water. When firm, unmold and serve with any fruit and sugar and cream, perhaps sprinkled with nutmeg.
