90% Hydration Einkorn Flour
Near-liquid dough territory. Extremely open, almost hollow crumb. Produces 'glass bread' effect.

Is 90% hydration right for Einkorn Flour?
Einkorn Flour's workable hydration range is 55–65%. Its absorption multiplier is 0.88× bread flour. 90% is above Einkorn Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 65%, or blend Einkorn Flour (40–60%) with bread flour for structural support.
Absorption math for Einkorn Flour at 90%
A recipe written for bread flour at 90% hydration, when substituted with 100% Einkorn Flour, becomes 79% effective hydration (because Einkorn Flour absorbs 12% less water). NO autolyse (gluten breaks down). Mix everything at once. Minimal folding (1-2 gentle folds). Shorter bulk (30-40% less time vs bread flour). Shape wet hands, handle minimally. Expect a slightly dense, tender crumb — not open or airy.
Technique at 90% hydration
Dough handling requires constant wet hands, bench scrapers, and oiled surfaces. Include 5% olive oil for lubrication. Pan-baked only. Expert-level technique.

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.
