Shaoxing Wine, also known as Shao Hsing or Chinese cooking wine, emanates from the city of Shaoxing in the Zhejiang province of China. It is an integral ingredient in Chinese cuisine, renowned for its unique ability to enhance and deepen the flavors of food. It's made from fermented rice, wheat and water, displaying an amber color and a distinct sweet, warm, and savory flavor profile that's slightly nutty.

Usage of Shaoxing Wine extends from marinades, braising liquids, and sauces, to stir-frys and soups, providing a depth of flavor that's not easily mirrored by other ingredients. Some popular dishes that might incorporate it include Dongpo Pork, Drunken Chicken, and various dumpling fillings. Shaoxing wine is also used in making mooncakes, a popular Chinese dessert.

Essential in achieving authentic flavors for dishes like mapo tofu, lo mai gai, and even humble fried rice, Shaoxing Wine offers a rich and robust dimension without overpowering the dish, transforming ordinary recipes into edible masterpieces. It is a must-have ingredient for anyone looking to explore the realms of Chinese cooking.

Although traditionally found in Asian grocery stores, its popularity has extended to mainstream supermarkets in the international aisle. If you find yourself in a bind without this quintessential cooking wine, a good substitute would be dry sherry or even cooking sake to replicate its signature umami effect. However, for the real impact of Shaoxing wine in your dishes, there is no true substitute. Store in a cool dry place in an air-tight jar or bottle once opened and use judiciously for adding an authentic touch to Chinese recipes.

Shaoxing Wine can usually be found in the Asian or international food section of a grocery store. If not there, it might also be located in the alcoholic beverages or wine section of the store. However, availability may depend on the store's size and the region's specific demographics. If it's not available in your local grocery store, you can also check at an Asian market or purchase it online.
