Here is a great recipe for crackers that are similar to saltines. This recipe yields about 120 crackers.
Preheat the oven to 375 degrees.
Combine flour, baking powder and shortening in a mixer. Once mixed, add milk and blend well.
Form a large round ball with the dough and split it into four separate sections.
Roll out one of the sections until it is about 1/8 of an inch thick.
Cut the dough into squares with a knife, pizza cutter or pastry roller with crinkled edges. Repeat with the three other sections.
Sprinkle salt (to taste) onto an ungreased cookie sheet and lay the dough on it. Using a fork, prick the dough repeatedly in 1/2-inch increments.
Bake for about 14-20 minutes, until the crackers are a golden brown.
