1 quart of flour.
3 tablespoonfuls butter.
½ teaspoonful soda, dissolved in hot water.
1 saltspoonful salt.
2 cups sweet milk.
Rub the butter into the flour, or, what is better, cut it up with a
knife or chopper, as you do in pastry; add the salt, milk, and soda,
mixing well. Work into a ball, lay upon a floured board, and beat with
a rolling-pin half an hour, turning and shifting the mass often. Roll
into an even sheet, a quarter of an inch thick, or less, prick deeply
with a fork, and bake hard in a moderate oven. Hang them up in a muslin
bag in the kitchen for two days to dry.
