Accurate fermentation made simple: this Hotbar proofing box features a built-in chip sensor and an internal bottom sensor to monitor conditions precisely.

Compact, user-friendly construction: the proofing box snaps together in seconds, folds flat for storage, and includes a zippered window so you can check progress without disturbing the controlled environment. Multi-use fermentation station: beyond bread, this proofer works as a warmer and controlled environment for fermenting yogurt, kefir, and other cultured foods. Consistent results every bake: whether you’re learning or experienced, this proofing box helps produce uniform texture and structure with minimal supervision.
