Buttery and flaky, these canapés are like little tarts, but much easier to make. Follow our topping suggestions—or try your own: sautéed mushrooms and stilton cheese, caramelized onions and anchovies ... let your imagination be your guide. Prep and Cook Time: about 45 minutes, plus 1 1/2 hours of chilling and cooling time. Notes: This dough is the ultimate kitchen workhorse. It's fast to make and will keep in the freezer for up to a week (let thaw 1/2 hour before rolling) or in the fridge for 3 days. You can also bake the dough a day ahead and top it just before serving. This recipe can easily be doubled, but if you want to triple or quadruple it, make 2 separate batches of dough.
