Is 55% hydration right for All-Purpose Flour?

All-Purpose Flour's workable hydration range is 6072%. Its absorption multiplier is 0.97× bread flour. 55% is below All-Purpose Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 60% for better extensibility.

Absorption math for All-Purpose Flour at 55%

A recipe written for bread flour at 55% hydration, when substituted with 100% All-Purpose Flour, becomes 53% effective hydration (because All-Purpose Flour absorbs 3% less water). Shorter autolyse (20-30 min) — longer autolyses over-soften the gluten. Fewer stretch-and-folds (2-3 sets) to avoid tearing the weaker gluten structure. Best for beginner hydration range 65-70%.

Technique at 55% hydration

Stiff dough, easy to handle. Use stand mixer for enriched versions. Low-hydration doughs tolerate mistakes well — good starting point for new bakers. Appropriate for pan-shaped loaves, enriched breads, and styles requiring dense texture like bagels and pretzels.

How the math works

Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.

Salt % is computed on total flour weight, not final-dough flour.
