What is First Clear Flour?
First clear flour is the high-protein wheat stream left after the pale “patent” flour is milled off — it comes from the outer endosperm, so it is higher in protein, ash, and minerals, with a slightly darker, cream-grey cast. Protein runs high (~15–16%), but the gluten quality is lower than patent bread flour, which is exactly why bakers reach for it in blends rather than alone. Its historic home is the Jewish deli rye: first clear's extra protein scaffolds the weak, pentosan-bound structure of rye to give a loftier rise and chewier crumb. It is also a classic bagel flour, where high protein plus low hydration builds the signature dense chew. Rarely used at 100% for open-crumb sourdough; it shines at 20–50% alongside rye, whole wheat, or spelt to add lift. Central Milling and King Arthur both mill a first clear.
How do you bake with First Clear Flour?
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.
What hydration % for First Clear Flour?
Baker's-percentage workable range: 66% — 78%. Absorption is 1.030× bread-flour baseline, so recipes written for bread flour need 3% more water when substituting First Clear Flour.
