You can also use shape and without holes, the main requirement is that it applies only to the fact that it should fit completely in a large diameter container.
Fill a large pot is the amount of hot water to reach the bottom of the colander or two-thirds covers the continuous capacity placed in it. It is important that the boiling water does not get into the containers with the products, otherwise the whole effect of the water baths will be lost, all the nutrients from the product will go into the water.

After boiling, reduce heat and cover the pan with a lid, this will keep inside the tank a sufficiently high temperature. The readiness of the product is determined by the sample and taking into account the recommendations of specific recipes. For vegetables requires 30-40 minutes, depending on their density. The longest stewed cauliflower and carrots. Meat can be cooked longer, but here a great role plays the thickness of the piece.
