Zucchini and Ricotta Galette

Make dough: Whisk together the flour and salt in a large bowl.

Sprinkle bits of butter over dough and using a pastry blender, cut it in until the mixture resembles coarse meal.

In a small bowl, whisk together the sour cream, lemon juice and water and add this to the butter-flour mixture.

With your fingertips or a wooden spoon, mix in the liquid until large lumps form. Pat the lumps into a ball; do not overwork the dough.

Cover with plastic wrap and refrigerate for 1 hour.

Make filling: Spread the zucchini out over several layers of paper towels. Sprinkle with 1/2 teaspoon salt and let drain for 30 minutes; gently blot the tops of the zucchini dry with paper towels before using. In a small bowl, whisk the olive oil and the garlic together; set aside.

In a separate bowl, mix the ricotta, Parmesan, mozzarella, and 1 teaspoon of the garlicky olive oil together and season with salt and pepper to taste.

Prepare galette: Preheat oven to 400 degrees. On a floured work surface, roll the dough out into a 12-inch round.

Transfer to an ungreased (or parchment lined) baking sheet.

Spread the ricotta mixture evenly over the bottom of the galette dough, leaving a 2-inch border.

Shingle the zucchini on top of the ricotta in concentric circles, starting at the outside edge.

Drizzle the remaining tablespoon of the garlic and olive oil mixture evenly over the zucchini.

Fold the border over the filling, pleating the edge to make it fit. The center will be open.

Brush crust with egg yolk glaze.

Bake the galette until the cheese is puffed, the zucchini is slightly wilted and the galette is golden brown, 30 to 40 minutes.

Remove from the oven, sprinkle with basil, let stand for 5 minutes, then slide the galette onto a serving plate.

Cut into wedges and serve hot, warm or at room temperature.
