Sourdough Starter Discard Recipe Calculator

You Can Add Sourdough Starter Discard to Almost Anything — "It Just Requires a Little Math". When replacing flour and water with sourdough discard it's important to maintain bakers percentages. This simple calculator will compute the amount of flour and water needed after the addition of your sourdough discard.

If I can't maintain baker's percentages, I will limit the amount of discard and flash a message indicating so. In any case, relax, don't worry, and have another slice of buttered bread.
