Is 75% hydration right for First Clear Flour?
First Clear Flour's workable hydration range is 66–78%. Its absorption multiplier is 1.03× bread flour. At 75%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.
Absorption math for First Clear Flour at 75%
A recipe written for bread flour at 75% hydration, when substituted with 100% First Clear Flour, becomes 77% effective hydration (because First Clear Flour absorbs 3% more water). Treat it as a strengthening flour, not a standalone. In rye blends, follow the rye's handling (short bulk, minimal knead). For bagels, work stiff and low-hydration. Its slightly weaker gluten rewards gentle, thorough mixing over aggressive kneading.
Technique at 75% hydration
The sweet spot for most hearth sourdough. Requires confident stretch-and-folds (3-4 sets). Wet hands essential for shaping. Cold retard improves handling and ear development during scoring.

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.
