Mesquite Crackers II

Mix the dry ingredients in a bowl. Cut in the butter until very fine. Add the milk & egg and mix to make a stiff dough. Knead thoroughly and then roll the dough very thin. Cut into squares or rounds and place on lightly buttered cookie sheers. Prick the crackers with a fork and then bake in a 400-degree oven for 10 minutes, or until very lightly browned. If desired, crackers may be sprinkled with coarse salt. (I dipped the small balls of dough into corn meal and then pressed them between two pieces of parchment paper in a tortilla press and then rolled them thinner with a rolling pin.)
