Baking with Sourdough Discard
When incorporated into buttery crackers, sourdough discard imparts a savory almost cheesy flavor that’s not overly tangy. Since you won’t use it to make bread rise, you can use unfed sourdough or sourdough discard straight from the refrigerator. Freshly fed sourdough will have a milder flavor than discard that’s been kept in the fridge for weeks, both will work but you’ll get a deeper flavor from older discard.

What You Need
Sourdough discard - Adds a delicious cheesy flavor to these crackers, since you aren’t using it for leavening you can use your starter directly from the refrigerator
Whole wheat flour - Imparts a nutty flavor and makes these crackers a bit healthier, feel free to substitute ancient grains like spelt and einkorn flour or all-purpose flour if that’s all you have in your pantry
Salt - Use kosher salt for the dough and flaky sea salt as a topping
Baking powder - Tenderizes these crackers, giving them a light and crisp texture, don’t leave it out or your crackers will be too tough
Butter - Makes these crackers rich and buttery
Spices and herbs - Get creative! Dried spices and herbs will add extra flavor to your crackers, optional but recommended

Step-by-step Instructions
I absolutely love making everything by hand and this recipe creates a dough that's fun to handle and easy to roll out. If you'd prefer to use a mixer, I've included instructions in the recipe card below.

1. Whisk the whole wheat flour, baking powder and salt together

2. Rub the butter into the flour mixture

3. Stir in the sourdough discard until you form a cohesive dough

4. Divide the dough and wrap each portion in plastic wrap and refrigerate for at least 30 minutes

5. Roll the dough out in between two sheets of parchment paper

6. Cut the dough into 36 to 42 squares

7. Top the dough with salt and prick each square with a fork

8. Bake the dough at 350 F for 20 to 25 minutes
Questions?
This recipe makes about 72 to 84 crackers, depending on how cut and divide the dough.
Absolutely! Simply use the same proportion of freshly fed sourdough starter in the recipe. Your starter won’t add a strong tangy flavor to your crackers, but it will still work.
If you don’t have a starter, but still want to try out this recipe, simply add 113 grams of all-purpose flour and 113 grams of water or milk to your batter. You won’t get the tangy, cheesy flavor that sourdough imparts to these crackers, but the recipe will still turn out.
If your dough is too sticky to roll out, try refrigerating it for a longer period of time.

Ingredients
Dough
- 120 grams whole wheat flour
- 6 grams salt Morton's Kosher Salt
- 5 grams baking powder
- 70 grams unsalted butter cold and cut into ½-inch cubes
- 226 grams sourdough discard cold and unfed

- herbs optional
- spices optional
Instructions
- To make the dough by hand: In a large mixing bowl, whisk together the whole wheat flour, salt and baking powder until no lumps remain. Using your fingertips, toss the butter into the flour, then squeeze the butter pieces and rub them into the flour mixture. Continue doing this until your mixture resembles coarse breadcrumbs, it’s ok if you have some pea-sized portions of butter-coated flour. Create a well in the center of your flour mixture, and pour the sourdough discard in the center. Using a wooden spoon or a spatula, stir the mixture together until fully incorporated. Lightly knead the dough until it clumps together into a ball. *Stand mixer instructions: With a paddle attachment, add in the whole wheat flour, salt, and baking powder and mix for 2 to 3 rotations to combine dry ingredients. Add in the butter and mix until it looks like wet sand. Make a well in the middle of the flour mixture and add in the sourdough discard. Mix on low until almost combined, do not overmix. Finish by mixing with your hands to incorporate all dry ingredients.
- Chill the dough: Divide the dough into two portions, weighing 210 grams each. Wrap each portion in plastic wrap and flatten it out into a disc (like you would a pie dough). Chill the dough for 30 minutes or up to 24 hours.
- Prep: Preheat the oven to 350 F while your dough chills. Cut out three 18 by 13 inch pieces of parchment paper, set aside.
- Roll out the dough: Lightly dust 1 piece of parchment paper with a little bit of flour. Place one portion of dough (keep the other portion in the refrigerator) in the center of the parchment paper and place another piece of parchment on top. Using your rolling pin, roll the dough out into a rough rectangle, about 12 by 10 inches in size (you don’t have to be totally exact).
- Cut and top: Peel off one piece of parchment paper (don’t peel the dough off the second piece of parchment). Using your pastry wheel, cut the dough into a grid with about 36 to 42 squares. Sprinkle flaky sea salt and herbs (if using), over the dough. Lightly press the toppings into the dough. Prick each square a few times with a fork (this will prevent your dough from rising as it bakes).
- Bake: Carefully transfer the parchment with the cracker dough onto a large baking sheet. Bake for 20 to 25 minutes, rotating halfway through. Your crackers are done when they feel completely dry and the edges begin to brown slightly. Don’t over bake or your crackers will burn.
- Enjoy and store: Let the crackers cool completely, then snap them off along the cut lines. Store crackers in an airtight container at room temperature for up to 1 month.
