A. Compatibility: This heavy-duty silicone cover is specially designed to be compatible with Anova. It may also be compatible with most sous-vide pots having an opening of 2 inches in diameter. It's advisable to check if it fits your cookware before placing an order. B. For a standard 10 1/2" pan: The lid can be placed slightly forward on one side without any gap, and it may fit the 10 1/2" size and smaller ones. This adds versatility to the type of container used in sous-vide cooking. It's recommended to measure your pan before purchasing. C. Adequate seal: Made of thick soft silicone, it is heavy enough to lie flat on top of the pan and maintain a good seal, even if the pan's diameter is a few inches smaller. D. Great for long-term cooking: It helps maintain a proper temperature and minimize evaporation. You may not need to get up in the middle of the night to fill a jar anymore. E. Bonus: It reduces the sound of water sloshing. Using a sous-vide lid may allow for faster preheating and reduce the overall heating time during cooking. F. Product: 1*Silicone Sous Vide Lid
