Why King Arthur All-Purpose Flour (11.7% Protein) Slumps at 80% (+8% Over 72% Cap)
King Arthur Unbleached All-Purpose Flour (11.7% protein, 0.48% ash) blends hard red wheats tested at 80% (390g water, 80.0%) for top American AP gluten index, though 0.61 base absorption caps safe water at 72%. Using 351g autolyse plus 39g bassinage (avoiding 400g / 81.8%) balances gliadin stretch and glutenin recoil. At the 80% (80.0%) mark using 390g water (351g + 39g) vs 400g (81.8%), King Arthur All-Purpose Flour holds a -8% margin against its 72% limit.
BASSINAGE & VWG RESCUE PROTOCOL: Because 80% (80.0% at 390g water) sits 8% above King Arthur All-Purpose Flour's 72% max (11.7% protein, 0.48% ash), 44g water weakens lamellae. Supplement 500g King Arthur All-Purpose Flour with 20g VWG or cut water to 346g.
