Sourdough baking uses baker's percentages where all ingredient quantities are expressed as a percentage of total flour weight. This allows recipes to scale easily to any batch size. The starter (levain) contributes its own flour and water to the dough.

공식

Hydration % = Water weight ÷ Flour weight × 100

단계별 가이드
