2 1/8 c unbleached all-purpose flour

Form dough into 1T up to 3T size ball, depending on how big you want your cookies. Hold dough ball with the fingertips of both hands, pull into two equal halves. Take the jagged surfaces where they were ripped from each other; and put them back together with the jagged bits facing upward. Put formed dough onto parchment paper-lined cookie sheet.
Bake until cookies the outer edges have started to harden yet centers are still soft, 14 to 18 minutes, smaller cookies may take less time.
Cool cookies on cookie sheets transfering to cooling racks after 10 minutes. Store in airtight container.
