The functionality discussed involves utilizing a multi-cooker, specifically one with a sous vide setting, to precisely control water temperature for cooking food sealed in bags. This method allows for consistent and even cooking, resulting in textures and doneness levels that are often difficult to achieve with conventional cooking techniques. For example, a tough cut of beef, cooked at a low, consistent temperature over a prolonged period, will become remarkably tender.
This technique offers numerous advantages, including enhanced flavor retention, reduced risk of overcooking, and the ability to batch cook meals for later consumption. Historically, water bath cooking relied on specialized equipment and was primarily used in professional kitchens. The integration of temperature control features into multi-cookers has made this approach more accessible to home cooks.
