King Arthur Baking Company Sourdough Crock

Stoneware provides a more stable, temperature-regulating environment for your starter compared to glass. Its opaque, thick-walled construction helps protect active cultures from light and sudden temperature fluctuations, which can lead to more consistent fermentation.

No, the lid is specifically designed to sit loosely to allow gases to escape during fermentation, which is essential for a healthy starter. It provides enough coverage to prevent debris from entering while maintaining the right humidity levels for your culture to thrive.

Yes, the ceramic construction is durable and dishwasher safe. You can easily clean it between feedings without worrying about damaging the material.

The two-quart capacity is ideal if you bake frequently or like to keep a larger reserve of starter on hand. It provides ample headspace for the starter to double or triple in volume during peak activity without overflowing, making it a practical choice for active bakers.

This crock is crafted from food-safe ceramic and is both BPA-free and PFAS-free. You can use it with confidence knowing it won't leach any unwanted chemicals into your starter.
