Which of the following techniques is most likely to enhance the texture of stir-fried vegetables?

Searing is a technique that enhances the texture of stir-fried vegetables by quickly cooking the outside of the vegetables at a high temperature, creating a crispy exterior while maintaining a tender interior. This fast cooking method helps to lock in moisture and flavor, resulting in a more appealing bite and an overall satisfying texture.

In contrast, boiling can lead to a loss of crispness and nutrients as vegetables may become waterlogged and mushy. Steaming also cooks vegetables gently but may not provide the same degree of texture contrast as searing. Blanching, while useful for quick cooking and preserving color, typically results in softer vegetables that may lack the desired texture that searing offers. Thus, searing is the most effective technique on the list for enhancing the texture of stir-fried vegetables.
