My neighbor, Kim, has been stir-frying, ever since I convinced her to move her wok from cold storage to stovetop. (She inherited a great wok, completely seasoned and beautifully charred black, from a friend years ago and once used it as a planter!) Now she regularly stops on her way to the market to consult with me about what ingredients to buy for that night’s stir-fry. With so many ingredients to choose from, it can seem daunting. I used to have the same problem matching ingredients until I started writing down and analyzing classic combinations. There is a logical method to the madness of ingredients selection.
