01Prepare the dough
In a large bowl, whisk together the flour, sugar, and salt. Using your fingers or a pastry cutter, rub the chilled butter into the flour mixture until it resembles coarse crumbs. Stir in the egg yolks, oil (or melted butter), wine (if using), vanilla and lemon zest. Mix until a dough forms, adding a splash of milk if the mixture seems too dry. The dough should hold together but not be sticky. Shape into a disk, cover, and refrigerate for 30 minutes to rest.
