Is 55% hydration right for Italian Type 00 Flour?
Italian Type 00 Flour's workable hydration range is 58–68%. Its absorption multiplier is 1.01× bread flour. 55% is below Italian Type 00 Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 58% for better extensibility.
Absorption math for Italian Type 00 Flour at 55%
A recipe written for bread flour at 55% hydration, when substituted with 100% Italian Type 00 Flour, becomes 56% effective hydration (because Italian Type 00 Flour absorbs 1% more water). Minimal autolyse (15-20 min) — fine grind hydrates quickly. For Neapolitan pizza: 60-62% hydration, 24-48h cold bulk, short proof, extreme heat bake. For bread: treat like AP or bread flour depending on protein spec.
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.
