Put in a saucepan one quart of fine, red, cleaned cranberries with a gill of water; place it on a hot stove and boil for fifteen minutes, then add five ounces of powdered sugar, and stir lightly with a spatula for five minutes. Remove it from the fire, pour it into a sieve over a vessel, and press well through with a wooden spoon. Transfer it into a stone jar, and use when required.
