Sous vide is a type of cooking method that uses a vacuum seal to trap the heat and moisture inside food, instead of cooking it at a high temperature like normal methods do. This means you can cook things like meat, fish, and vegetables to the perfect level of doneness.

Joule is a sous vide system from ChefSteps that has been designed to help you cook anything you want at home with just one app. The Joule App lets you choose what you want to cook and sets the temperature, then watches it cook until it reaches the desired level. Then it lets you know how much time is left in the cooking process, so you know when to put the food on the table. You can also get step-by-step instructions to help you better understand how to prep your meal.
