Frequently Asked Questions

What is baker's percentage?

Every ingredient is expressed as a percentage of the total flour weight. Flour is always 100%. So 75% hydration means 750g water per 1000g flour.

How much starter should I use?

15-25% of flour weight is typical. More starter = faster fermentation. Less starter = longer, more complex flavor development.
