This warming mat provides a stable, controlled warmth for proofing sourdough and other doughs. It offers adjustable temperature from 70 to 100 degrees Fahrenheit with 1-degree precision, helping maintain the steady heat needed for reliable fermentation. Keeping the environment around 75 to 82 degrees Fahrenheit is ideal for faster fermentation and smoother dough texture, which can shorten prep time compared with cooler setups. The mat helps create a consistent, warm space for jars and containers, reducing temperature swings in cold kitchens. It is designed to accommodate fermentation jars ranging from small to large, with a heating zone that supports a variety of batch sizes. The unit is compact and durable, with a simple US plug design suitable for home kitchens, counters, or drawers. In use, a light sits near the controls to indicate status, while a timer can be set up to 12 hours with an auto shut-off, and a memory feature recalls last settings for quick restart. It uses efficient heating technology to reach target temperatures quickly and maintain them with low power draw, allowing safe operation and energy awareness. Jar not included, so you can use standard fermentation jars for your recipes. With straightforward controls and quiet operation, it fits into a busy kitchen. Material: Aluminum.
