All you need to master the art of air-tight bags and temperature-controlled cooking is this sous-vide kit. Instead of preparing and cooking a meal every night, season and marinate your ingredients one day, seal them in air-tight bags or containers and store them in the fridge until you’re ready to cook. You’ll never experience a bite of overcooked meat or undercooked vegetables ever again. Each bag and container features a QR code that can be used with Zwilling’s Culinary World application, which suggests recipes and will let you know when your food is going to go bad. Make sure to check out the extensive sous-vide guide on the brand’s website if you’re feeling intimidated by this revered French cooking technique.
