A sous vide cooker is a kitchen appliance designed for precise cooking using the sous vide technique. This method involves sealing food in a vacuum bag and immersing it in a water bath at a controlled temperature. This allows for even cooking and enhances the flavors and textures of the food. Sous vide cookers come in various forms, including immersion circulators and water ovens. They are popular among both home cooks and professional chefs for their ability to produce consistent results. With a sous vide cooker, meals can be prepared in advance and held at the desired temperature until ready to serve.
