How to Convert undefined to undefined

  1. Enter total flour weight in grams.
  2. Set target hydration percentage (70% to 80%).
  3. Set starter percentage (15% to 25%).
  4. Set salt percentage (2.0% to 2.2%).

Worked Culinary Example

Scenario: 500g flour loaf at 75% hydration, 20% starter, 2% salt.

  1. Water = 500 × 0.75 = 375g.
  2. Starter = 500 × 0.20 = 100g (50g flour + 50g water).
  3. Salt = 500 × 0.02 = 10g.
  4. Total Dough = 500 + 375 + 100 + 10 = 985g.
Result: 500g flour, 375g water, 100g starter, 10g salt = 985g dough.

Quick Reference Conversion Table

undefined undefined
65% Hydration Stiff, easy to handle, holds shape well
70% Hydration Standard artisan sourdough, good balance
75% Hydration Open crumb, requires strong gluten structure
80%+ Hydration Very wet, requires coil folds and high protein flour

Common Measuring Mistakes to Avoid

Forgetting starter hydration

A 100% hydration starter contributes equal parts flour and water to the dough.
