Sourdough discard is the portion of your sourdough starter that you remove before feeding the remaining starter with fresh flour and water. Instead of throwing it away, you can use it in countless recipes for added flavor, texture, and to reduce food waste.

Yes! Cold discard works perfectly in most recipes. For recipes that require leavening (like pancakes or waffles), you may want to let it come to room temperature first, but for crackers, flatbreads, or cookies, cold discard is totally fine.

Sourdough discard can be stored in the refrigerator for up to 1–2 weeks in a sealed container. Over time, it may develop a darker liquid on top (called "hooch") — simply stir it back in or pour it off before using. If it develops mold or an off smell, discard it entirely.

Active starter has been recently fed and is bubbly, doubling in size — it's used as a leavening agent for bread. Discard is unfed starter that has fallen and is less active. While discard won't leaven bread on its own, it adds wonderful tangy flavor and moisture to quick breads, crackers, pancakes, and more.

Absolutely! Freeze discard in an airtight container or freezer bag for up to 3–4 months. Thaw overnight in the fridge before using. Freezing is a great way to accumulate enough discard for larger recipes or to take a break from baking without wasting your starter.

Most sourdough discard recipes call for anywhere from ½ cup (120g) to 1 cup (240g) of discard. The exact amount depends on the recipe — pancakes and waffles typically use about 1 cup, while crackers may use less. Always follow the specific recipe for best results.

Using discard reduces food waste, saves money on ingredients, and adds incredible depth of flavor to your baking. The fermented nature of discard brings a subtle tanginess and complexity that enhances everything from sweet banana bread to savory crackers. It's also a great way to experiment with new recipes!
