Tips for Steaming Vegetables

To make the most of steaming:

* Be sure the rack sits at least one inch above the water in the wok. Have boiling water on hand to replenish any that evaporates.

* Steam marinated or sauced items in a pan or on a plate to save the juices.

* If the lid of the wok is loose, wrap a wet towel around it to seal in the steam.
