Cookies may seem odd in a vegetable galette, but Italians often use amaretti to enhance squash—and it works with sweet potatoes, too. Whereas the potato and kale galette is savory, this is a little sweet, so it's worth making both.
Cooks' notes:
•If you are also making roast capon (page 190), galette can be baked at the same time in upper third of oven.
•Galette can be made 2 days ahead and cooled, uncovered, then chilled, wrapped in foil. Unwrap and transfer to a baking sheet, then reheat in a 375°F oven until heated through, about 15 minutes.
