Which cooking method uses steam to prepare food?

The correct answer is steaming, which is a cooking method that utilizes steam to cook food. This technique involves placing food above boiling water or in a steam basket where the steam envelops the food, cooking it gently without direct contact with water. Steaming is particularly effective for preserving the nutrients, color, and texture of vegetables and proteins. Foods cooked this way typically maintain moisture and do not require additional fats, making it a healthier cooking option.

In contrast, boiling involves submerging food in water, which can lead to nutrient loss. Grilling utilizes direct heat from below, often resulting in a Charred exterior, while roasting involves cooking food in an oven with dry heat, which can enhance flavors through browning but does not involve steam. Each of these methods offers unique benefits and characteristics, but steaming specifically highlights its use of water vapor to cook food.
