When using a food processor to make dough, you want the machine running for the least amount of time possible once you add the water. This will help keep the dough flaky. You can let the dough form a ball, but it will be a tougher crust. If you stop the machine once the ingredients are combined and flaky, you can press them together by hand for more tender results. I press them together while wrapping the dough in plastic wrap.
