Ingredients

  • 1 1/4 cups all-purpose flour
  • 1/4 cup yellow cornmeal
  • 1/2 teaspoon kosher salt
  • 3 tablespoons sugar
  • 10 tablespoons unsalted butter, cut into small pieces and well chilled
  • 4 to 5 tablespoons ice water
  • 1 large egg yolk beaten with 1 teaspoon water (for brushing the tart)
  • 5 or 6 peaches, peeled and sliced (about 5 cups)
  • 1 tablespoon fresh lemon juice
  • 1/4 cup sugar
  • 1 tablespoon all-purpose flour
  • 1/4 teaspoon ground ginger
  • 1/2 teaspoon vanilla extract
  • Pinch of kosher salt

Method

  • To make the galette dough:
  • In a stand mixer using the paddle attachment, combine the flour, cornmeal, salt, and 1 tablespoon sugar.
  • Add the cold butter all at once.
  • Mix on low speed until the mixture begins to resemble coarse cornmeal with some larger chunks.
  • Using a fork or your fingertips, add the ice water 1 tablespoon at a time, tossing it with the dough.
  • After the fourth tablespoon has been added, squeeze a small amount of dough in your hand.
  • If the mixture does not stay together and looks dry, add another tablespoon of water.
  • If necessary, add even more water, drop by drop, until the dough just holds together.
  • Dump the dough onto a piece of plastic wrap and gather it up to form a flat, round disk.
  • Wrap it well in the plastic wrap and refrigerate it for at least an hour.
  • To make the filling:
  • Combine all of the filling ingredients in a large bowl and toss gently to combine.
  • To assemble and bake the dough:
  • Heat the oven to 400F.
  • Line a baking sheet with parchment paper.
  • On a floured surface, roll out the dough into a 14- to 15-inch circle; trim any rough edges, if necessary, to maintain a round shape.
  • Transfer the dough to the baking sheet, allowing any excess to hang over the sides.
  • Pour the filling onto the dough, leaving a 2-inch edge of dough with no filling on it.
  • Fold the dough over the fruit toward the center, pleating and overlapping as necessary.
  • Brush the edges of the dough with the egg wash and sprinkle the galette with the 2 tablespoons sugar.
  • Bake until the crust is golden brown and the filling is bubbling, 45 to 50 minutes.
  • Remove from the oven and let cool a little before cutting.
