Answer:
It is a cooking method where you immerse vacuum sealed food into water to slow cook it to a desired temperature. There is a thermometer in the water and another in the food. The water is heated to a specific temperature, say 160 degrees, until the internal temperature of the food reaches the desired temperature. This takes a long time and is monitored by a computer. Once the food is cooked the water is drained and replaced with cold water, say 30 degrees, to cool the product for storage.
