King Arthur'S English Digestive Biscuits

Preheat your oven to 350°F. Lightly grease a couple of baking sheets, or line them with parchment., Measure the flour and baking powder into a mixing bowl. With a pastry blender, two knives, or your fingertips, rub the butter into the flour mixture. Toss in the sugar and enough milk to make a stiff dough. Gently and briefly knead this mixture on a floured surface until smooth. (All this can be done almost instantly in a food processor.), Roll the dough out to a bit more than 1/8" thick, and cut into any desired shape. Traditionally, these "biscuits" are round and about 2 1/2" in diameter., Place the cutout cookies on the prepared baking sheets. Prick them all over with a fork, and bake until pale gold, between 15 and 20 minutes., Remove the cookies from the oven, and cool right on the pan. Store airtight at room temperature for up to a week; freeze for longer storage.
