The Le Creuset Butter Crock has an airtight seal to prevent butter from spoiling while keeping it at the perfect temperature for spreading and cooking. The crock is inspired by classic designs, blocking out air that can ruin butter while approximating room temperature to keep the butter soft without melting. Crafted from premium stoneware and finished with a vibrant glaze which is easy to clean, dishwasher-safe, and resistant to chips, scratches and stains.
