How is food prepared using the steaming method?

Food prepared using the steaming method involves surrounding food in steam in a confined space. This technique utilizes water that is heated to produce steam, which then cooks the food by gentle convection. Steaming is a healthy cooking method since it doesn't require added fats, helping to preserve the food’s flavor, nutrients, and color. It is particularly effective for vegetables, fish, and even some meats, as it locks in moisture and allows the food to cook evenly without becoming soggy.

In contrast, boiling involves submerging food directly in water, which can result in nutrient loss. Microwaving heats food using electromagnetic radiation instead of steam, which is a different method altogether. Layering food in a casserole dish usually entails baking or slow cooking, which uses dry heat, rather than steam. Thus, the steaming method is specifically characterized by the use of steam to cook food, distinguishing it from the other cooking techniques listed.
