Knead well and finely together in a vessel one pound of good flour with six ounces of fresh butter, one gill of cold water, and a saltspoonful of salt. After ten minutes, when it becomes soft, roll it into a flat, circular cake - using a rolling-pin, well floured, to prevent its adhering. Place it in a baking-pan. Bake in a very slow oven for thirty-five minutes. When a nice light color, remove and let it cool. Serve it on a dessert-dish, over a folded napkin.
