Biscuit dough can be prepared in a food processor.  However, you need pulse each addition of the ingredients until just blended.  If you overprocess, this will will toughen the biscuits.

Rerolling can make biscuit dough tough.  You should try and cut as many biscuits as possible from the first rolling.

When biscuits are placed 2 inches apart on a cookie sheet, they will bake to a crisp, firm finish. When spaced closer together, the biscuits will be soft and tender.

To prevent biscuits from flattening when they are being cut, flour the biscuit cutter before cutting each biscuit.
