Rustic Fruit Galette
Galette Dough
  1. In a small bowl, combine sour cream & ice water; set aside. In a large bowl, whisk together flour, cornmeal, sugar & salt. Using a pastry blender or finger tips, cut in butter until mixture resembles BOTH coarse crumbs & small peas. Sprinkle the cold sour cream mixture over the dough, 1 Tbsp at a time, tossing with a fork to evenly distribute it. After you have added all the sour cream, dough should be moist enough to stick together when pressed; if not, add additional cold water, 1 tsp at a time. Do not overwork dough.
  2. Press dough into a disk shape & wrap in plastic wrap. Refrigerate for at least 2 hours. The dough can be kept in the refrigerator for a day or two or it can be wrapped airtight & frozen for a month. Thaw, still wrapped in refrigerator.
Fruit Filling
  1. In a bowl, toss together the fruit, all but 1 Tbsp of the sugar, salt, lemon juice & zest & cornstarch.
  2. Preheat oven to 375 F. Line a baking sheet with parchment paper. On a lightly floured work surface, roll out the chilled dough into a circle & set on baking sheet. Place the fruit filling in the middle, leaving a border of 1 1/2 to 2-inches. Gently fold pastry over the fruit, pleating to hold it in. Brush pastry with egg wash. Sprinkle the reserved 1 Tbsp sugar over the crust.
  3. Bake 35-45 minutes until the filling bubbles up & crust is golden. Cool for at least 20 minutes on a wire rack before serving. Best served warm or at room temperature.
