The most popular and the quickest method for cooking meat, fish, vegetables, fruits and light desserts, is to suspend over boiling water, cover tightly and cook in the steam. This method may also be used for reheating and thawing foods.

A longer method is cooking in a basin, bowl or paper or foil parcel over hot water. Foods are sealed within pleated wax paper or foil and secured with string. This is done to allow for expansion as the steam fills the parcel or basin. The string secures the paper to the basin and gives a tight fit to prevent steam escaping. Food cooks in its own juices, since the boiling water and steam do not come into direct contact with it. This method gives an exact and even cooking temperature throughout the cooking time, which is why it is used for melting chocolate and other tasks requiring consistent heat.

In the Oriental method of steaming rice, which is used for dishes such as risotto and paella, the rice is immersed in water or stock, covered, and steamed until the liquid has been absorbed and the rice is cooked.

Ensure the ingredients used are of the best quality and in perfect condition. Choose lean meats which will be tender and not require lengthy cooking. Trim away excess fat before using and always cut across the grain for extra tenderness.

Ensure the lid fits well to prevent the steam escaping and thus prolonging cooking time.

When choosing fruit and vegetables, look for unblemished skins and good color. Do not use “old” or bruised fruits, because steaming enhances flavors and aromas and any slight taint in a food will be accentuated.

Make sure foods to be cooked together are of a similar or even size so that they will cook in the same amount of time. This applies to chopped foods and meat, fish or poultry portions.

Do not allow the liquid in the base compartment to touch the food, or the food will boil and not steam. Suspend it at least 1 inch (2.5 cm) above the liquid.

Liquid levels in the base of the steamer should be maintained for constant cooking, although it should never be more than two-thirds full. Top up with boiling liquid to maintain cooking.

Cook food in a single layer or adjust cooking times accordingly, as cooking will be slower.

Arrange foods in the steamer compartment with space in between to allow steam to circulate and cook more efficiently. Always defrost frozen meats, fish and poultry before cooking, to allow for correct and complete cooking within the recommended times.

Place meats, fish, or juicy foods in the bottom tiers so that they cannot drip onto foods below.

Allow an extra five minutes for foods cooked in upper tiers because they are further away from the steam.

Finally, be sure to continue cooking foods that are not cooked through or not cooked to your liking, despite having been cooked for the recommended cooking time.
