Homemade Crisp Crackers Recipe

In a large bowl, combine the first seven ingredients; cut in butter until crumbly. Stir in cheese. Gradually add water and vinegar, tossing with a fork until dough forms a ball. Wrap in plastic wrap and refrigerate for 1 hour or until firm. Divide into six portions. On a lightly floured surface, roll each portion into an 8-in. circle. Cut into eight wedges and place on greased baking sheets. Bake at 375 ° for 17-20 minutes or until edges are lightly browned. Cool on wire racks. Store in an airtight container.
