Blueberry and Blackberry Galette with Cornmeal Crust
The rich, buttery pastry dough is easy and forgiving. Simply roll it out onto parchment paper with a lightly floured rolling pin, and then use the parchment to transfer it to a baking sheet. If you're lucky enough to find wild blueberries like the ones that grow in Maine, use them in this rustic summer tart.
