Joyce Chen - Chinese-American Chef, Author & TV Personality
On Chinese cooking (passed on through her daughter, Helen Chen): Canola oil is perfect for stir-frying. It is low-acid, low in saturated fat and flavorless. Sesame oil is only used as a flavoring tool, after the ingredients are cooked. Choose ginger that is hard with tight skin. Never use mirin. Dry sherry can be used as a substitute for Chinese rice wine.
