Is 78% hydration right for Khorasan (Kamut) Flour?
Khorasan (Kamut) Flour's workable hydration range is 60–70%. Its absorption multiplier is 0.97× bread flour. 78% is above Khorasan (Kamut) Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 70%, or blend Khorasan (Kamut) Flour (40–60%) with bread flour for structural support.
Absorption math for Khorasan (Kamut) Flour at 78%
A recipe written for bread flour at 78% hydration, when substituted with 100% Khorasan (Kamut) Flour, becomes 76% effective hydration (because Khorasan (Kamut) Flour absorbs 3% less water). Medium autolyse (30-45 min). 3 stretch-and-folds max. Similar handling to emmer. Pairs beautifully with whole wheat at 50/50 ratio for depth without density.
Technique at 78% hydration
Upper range of 'standard' hearth hydration. Benefits from high-extraction flour which tolerates the hydration. Use coil folds instead of stretch-and-folds to build structure without deflating. Cold retard mandatory.

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.
