What cooking technique involves sealing food in a bag and cooking it in a water bath?

The cooking technique that involves sealing food in a bag and cooking it in a water bath is known as sous vide. This method allows for precise temperature control and results in evenly cooked food. The food is typically vacuum-sealed, and then submerged in a water bath that maintains a constant temperature, allowing the food to cook slowly and thoroughly without overcooking.

Sous vide is popular for its ability to enhance flavors and retain moisture since the food is sealed away from the air. It is particularly useful for cooking meats, vegetables, and even eggs, resulting in textures that are difficult to achieve through traditional cooking methods. This technique has gained significant popularity in both professional kitchens and among home cooks looking for consistent and high-quality results.
