Professional bakers know that the ability to control yeast fermentation with low, humid heat makes for the best flavors in breads. This countertop box produces the optimal proofing environment for home-baked breads, then folds flat for easy storage. Set the digital temperature low for a long, slow rise or pre-fermentation. Turn up the heat to give yeast a boost on a cold day. This proofer also makes yogurt, melts chocolate, softens butter—and it's a great way to proof our frozen croissants and other Galaxy Desserts overnight.
