Why King Arthur All-Purpose Flour (11.7% Protein) Slumps at 85% (+13% Over 72% Cap)

King Arthur Unbleached All-Purpose Flour (11.7% protein, 0.48% ash) blends hard red wheats tested at 85% (418g water, 85.09%) for top American AP gluten index, though 0.61 base absorption caps safe water at 72%. Using 376g autolyse plus 42g bassinage (avoiding 425g / 86.4%) balances gliadin stretch and glutenin recoil. Scaling King Arthur All-Purpose Flour to 85% (418g main water, 376g autolyse, 42g bassinage) locks 85.09% across 550g flour (-13% from 72% max vs Bob's Red Mill Bread Flour).

PAN-PROOF OR FORTIFY (85% > 72% Cap): On 500g King Arthur All-Purpose Flour (11.7% protein, US Hard Red Blend), 418g main water locks 85.09% (85%) yet leaves 72g unbound water (+13% over cap). Add 33g VWG, pan-bake as focaccia, or use 346g water.

4-Step Autolyse, Bassinage & Coil-Fold Protocol for 500g King Arthur All-Purpose Flour @ 85%

  1. Endosperm Swelling (King Arthur All-Purpose Flour / 11.7% Prot): Combine 500g King Arthur All-Purpose Flour and 376g water (75% soak) for 45 min.
  2. True-85% Calibration (418g W + 100g Levain): Incorporate 100g ripe culture, 11g salt, and 42g reserved water across 550g total flour (85.09%).
  3. Lamination & Coil Cadence (0.48% Ash): Perform 1 bench lamination and 3 coil folds at 30-min intervals on your 85% King Arthur All-Purpose Flour dough.
  4. Overnight 38Β°F Retardation: Arrest fermentation at +50% rise, stitch in a breathable liner, chill 14 hrs, and bake 20m covered + 22m uncovered.
