How can I achieve the best results when velveting chicken?

To achieve the best results when velveting chicken, it is important to marinate the chicken in a mixture of egg whites, cornstarch, and seasonings for at least 30 minutes before cooking. This process helps to tenderize the chicken and create a velvety texture. Additionally, make sure to cook the chicken quickly in hot oil or water to maintain its juiciness and prevent overcooking.
