That depends on the size of the vessel you’re cooking with. The general requirement is that the food in the pouches should be completely submerged in the water. To ensure even cooking, we suggest using the pouch rack. This will allow you to cook a larger quantity of food and even temperature control throughout the bath. For example; in a 10 to 15-liter bath, you should be able to accommodate 15-20, 6-ounce portions. For at 20 to 30-liter bath, you can accommodate 30 to 40 6-ounce portions.
