About Dough hydration

Dough hydration is the baker's percentage of water relative to flour: water weight ÷ flour weight × 100. Example: 350 g of water and 500 g of flour gives 70% hydration.

Higher hydration doughs are stickier and give a more open crumb; lower hydration doughs are easier to handle.
