Sous vide works by surrounding your food in a precisely temperature-controlled water bath until you're ready. Just attached the cooker to any water-filled pot, put your food in a sealable bag, and set the time and temperature. The precision cooker heats and circulates the water to a precise temperature, cooking food with scientific temperature accuracy that creates maximum tenderness and moisture retention (never overcooking). The Anova Precision Cooker also features a full-service app with guides, recipes, and features that allow you to start, stop, and monitor your cook via Bluetooth from your mobile device.
