Graphene Heating System: The graphene heat transfer system quickly provides heat to the bread proofing basket, allowing it to speed up fermentation. Compared to traditional Banneton proofing baskets, the jabbus silicone batter bowl reduces fermentation time, giving you a whole new baking experience. Even in the coldest winter, fermentation can be completed in just 30-60 minutes. No more waiting around—speed up your dough’s rise!
