Berry-Filled Sourdough Discard Doughnuts
Makes about 12 doughnuts
  • ¼ cup (60 grams) warm water (105°F/40°C to 110°F/43°C)
  • 2 packages (14 grams) active dry yeast
  • 6 cups (750 grams) all-purpose flour, divided
  • 1 cup (240 grams) warm milk (105°F/40°C to 110°F/43°C)
  • ¾ cup (188 grams) sourdough starter discard, room temperature
  • 3 cups (600 grams) granulated sugar, divided
  • 2 large eggs (100 grams)
  • ⅓ cup (76 grams) unsalted butter, softened
  • 1½ teaspoons (4.5 grams) kosher salt
  • Vegetable oil, for frying
  • 2 cups (340 grams) Berry Crème Fraîche (recipe follows) or ½ cup (148 grams) Berry Jam (recipe follows)
  1. In the bowl of a stand mixer fitted with the paddle attachment, stir together ¼ cup (60 grams) warm water and yeast by hand. Let stand until mixture is foamy, about 5 minutes. Add 3 cups (375 grams) flour, warm milk, sourdough discard, ½ cup (100 grams) sugar, eggs, butter, and salt, and beat at medium speed until smooth, about 3 minutes. Beat in enough remaining 3 cups (375 grams) flour, starting with around 1 cup (125 grams), until a soft dough forms. (Dough will be sticky.) Switch to the dough hook attachment. Beat at medium speed until dough is smooth and elastic, 6 to 8 minutes.
  2. Lightly oil a large bowl. Place dough in bowl, turning to grease top. Cover with plastic wrap, and let rise in a warm, draft-free place (75°F/24°C) until doubled in size, about 1 hour.
  3. Line baking sheets with parchment paper.
  4. Lightly punch down dough, and turn out onto a lightly floured surface, and roll to ½-inch thickness. Using a 3¼-inch round cutter dipped in flour, cut dough, and place 1½ inches apart on prepared pans. Loosely cover with plastic wrap, and let rise in a warm, draft-free place (75°F/24°C) until doubled in size, about 2 hours.
  5. Place remaining 2½ cups (500 grams) sugar in a shallow dish. In a skillet or deep fryer, pour oil to a depth of 2 inches, and heat over medium heat until a deep-fry thermometer registers 350°F (180°C).
  6. Fry doughnuts, two at a time, until golden brown, 1½ to 2 minutes, turning every 30 seconds. Transfer hot doughnuts to sugar, turning to coat. Let cool completely on a wire rack.
  7. Using a small knife, cut a slit in the side of each doughnut. Place Berry Crème Fraîche or Berry Jam in a pastry bag fitted with a round tip. Pipe filling into doughnuts. Serve immediately.
