Scale
Process
KitchenAid Artisan with spiral hook: combine on low about 2 minutes, rest 20 minutes, two folds in the first hour, bulk to roughly 75-100% rise, cold retard 12-18 hours, pan and proof 45-90 minutes.
Bake
450-475 F until deeply golden and crisp.
Outcome
A carefully reconstructed sourdough conversion of the original 400 g flour / 190 g potato benchmark. No separate final-bake verdict preserved.
Next action
Treat as a distinct high-potato branch, not a replacement for Signature Version 1.
