Red cooking is a type of cuisine from China in which the ingredients are simmered over a low flame with lots of soy sauce, rock sugar and rice wine.
Red cooking, known in Mandarin as hong shao, is rarely seen in the Western world but it's a popular form of cooking throughout China. Though linked to Shanghai, Jiangsu and Zhejiang provinces, it has its variations everywhere in that country.
By the way, it is sometimes also referred to as red stewing or red braising.
In some places in China, anything that is soy sauce-braised is considered "red cooked." The Cantonese are known to use the leftover soy poaching sauce from one recipe and reconstituted with more soy sauce, rice wine and spices in another dish. This is what I've provided in the recipe below.
Red cooking, simply put, uses a main protein such as pork, chicken, beef, tofu, duck or wheat gluten (sometimes even carp fish) which is simmered over a low flame with dark soy sauce, rice wine, rock sugar, stock and other fragrant additions such as scallions, ginger, black cardamom, five-spice powder, star anise and cinnamon.
This stick-to-your-ribs cuisine is the equivalent of the Western Sunday night dinner. Although the food is hardly red in colour (more brownish red), for the Chinese, the colour is blessed, bringing luck and fortune.
One thing to remember, dark soy sauce is a key ingredient since it is thicker and sweeter than the regular kind.
Red-cooked dishes are often paired with stir-fried veggies, something light to go with a heavy meal. Other dishes to pair with a red-cooked meal include: Stir-Fried Pea Shoots, Steamed Tofu, Bean Sprout & Green Bean Salad, Hainanese Chicken Rice and Lemongrass Chicken.
