Features: Heat Resistant for Baking: The oven safe proofing basket is designed to withstand a wide range of temperatures, suitable for both cold proofing in a refrigerator and for use in a preheated oven. This versatility allows the sourdough baking supplies to support the entire proofing-to-baking workflow if needed Simple Cleaning Process: Cleaning the oval proofing bowl typically involves brushing out any leftover dry flour. If dough sticks, allowing it to dry and then brushing it off is often sufficient, as the non-porous silicone does not absorb water or odors, simplifying maintenance Specifications: Material: Silicone Color: Purple, green, yellow, blue Size: about 9.65x3.5x6.5inch Package includes: 4 x Silicone Bread Proofing Baskets Notes: Manual measurement, please allow slight errors on size.
