A better solution for sous vide cooking chefs with ANOVA cookers where water bath evaporation is annoying. You don't have to worry about the water evaporation as the lid miniminzes the heat loss and steam loss by firmly covering the container. Cook long and you don't have to refill water, particularly at night. A sous vide lid for the most common used container - Rubbermaid 12 18 22 Qt container. Precise size for both Anova sous vide cookers and Rubbermaid containers. Minimum Heat Loss, sous vide cooking requires very accurate water cooking temperature where heat loss could be a big factor that makes failure of cooking. Other than sous vide balls this lid is insulated, with only 5 ventilation outlets, to minimize heat loss. Side mount or corner mount available, since ANOVA is stirring the water to make water heat exchange, sometimes it is better to use a lid with side mount (ASIN:B071L6NN6M) and sometimes it is better to use a lid with corner mound (ASIN:B071L6PRY8). Very easy access to refill or remove food. The EVERIE SOUS VIDE LID is designed to be foldable in the center while cooking, so you could easily fold it to check the contents or add foods where some recipes require multi cooking timing, for example a beef steak requires 1,5 Hour cooking while another 2 eggs in the same recipe requires 30 minutes.
