90 crackers


  • 1 cup whole wheat flour (120 g)

  • ¼ cup seeds (use one or a mix of poppy, flax, amaranth, sesame, quinoa, and/or chia)

  • 1 teaspoon whole seeds and/or spices, crushed (crushed fennel seeds, caraway, or za'atar)

  • 1 teaspoon kosher salt

  • ¾ cup sourdough starter discard (210 g)

  • 3 tablespoon extra-virgin olive oil

  • 1 - 2 tablespoon water (optional)

  • Flaky sea salt, optional


  1. In a large bowl mix together flour, seeds, spices, and salt. Add sourdough starter and oil; mix until a smooth, uniform (not sticky) dough forms. (If mixture seems too dry, add water, a little at a time, until dough is smooth and firm, and not sticky.) Let rest, covered, 45 minutes.

  2. Preheat oven to 350°F. Divide dough into thirds. On a piece of parchment paper roll one portion of dough into a 10x8-inch rectangle. Using a pastry cutter, cut dough into 1 1/2-inch squares. (There is no need to separate crackers after cutting.) Prick each square with a fork. If using, brush lightly with water and sprinkle with flaky sea salt. Transfer crackers and parchment to a baking sheet.

  3. Bake crackers 15 minutes or until golden and crisp. Transfer crackers with parchment to a wire rack to cool. Repeat with remaining dough. Store cooled crackers in an airtight container at room temperature up to 2 weeks.
