What to Do with Sourdough Discard

Every feeding starts by removing most of the old starter, and pouring that into the bin feels terrible. Good news: discard is perfectly good fermented batter, and some of the best quick bakes are built on it.

What discard actually is

Discard is simply unfed starter, flour and water already broken down by fermentation, with a mild tang. It will not raise bread on its own (the yeast is spent), but as a flavor and tenderness ingredient it is excellent.

How to store it

Keep a dedicated jar in the fridge and add each day's discard to it. It holds for about a week, growing tangier every day. When the jar smells sharper than you like, it is cracker time (acidity shines there).

The best uses, easiest first

Make less discard in the first place

The smarter long-term move: keep a smaller starter. Maintaining 30 g instead of 200 g means discarding a spoonful, not a cupful, and scaling up only the day before a bake. Fridge storage with weekly feedings shrinks the waste further.

Rule of thumb: discard replaces equal weights of flour + water in any recipe (a 100 g scoop of 100% hydration discard = 50 g flour + 50 g water). Adjust the recipe's flour and liquid down accordingly.
