Frequently Asked Questions
What is Baker’s Hydration percentage?
Baker’s percentage defines all ingredient weights relative to total flour weight (100%). A 75% hydration dough contains 75g of water for every 100g of total flour.
How does starter hydration affect the recipe?
A standard 100% hydration sourdough starter consists of equal parts flour and water by weight (50% flour, 50% water), which is factored into the total dough formula.
