Perfect Sourdough Calculations
Sourdough baking requires understanding how your starter contributes to the final dough. Our calculator accounts for the flour and water in your starter, giving you accurate measurements for consistent, delicious loaves.
How Starter Affects Dough Calculations
Sourdough starter contains flour and water that must be factored into your total dough calculation. If you use 100g of 100% hydration starter, you're adding 50g flour and 50g water. Our calculator adjusts the remaining flour and water to achieve your target hydration.
