When Sweet, Salty, Sour and Bitter are Just not Enough

Vegetarian Stock

As an open-minded omnivore, I enjoy vegetarian dishes as much as meat dishes. On many occasions I’ve successfully made vegetarian dishes for my vegetarian friends. Many were surprised at the diversity of Chinese vegetarian dishes and commented how flavorful and hearty they were. The key to a rich tasty vegetarian dish is to make use of what is known as umami, which is a Japanese word used to express the fifth taste in addition to the generally accepted four tastes of sweet, salty, sour and bitter. In Chinese umami is known as xian (鮮) and making stock full of umami is the basis for a successful vegetarian dish.

Although the concept of an umami taste did not become commonplace in the West until recently, it has been recognized in Asian culinary culture as a pleasant savory taste for millenniums. In 1908 a Japanese scientist Dr. Kikunae Ikeda of Tokyo Imperial University successfully isolated a glutamate compound from kombu (a type of kelp). The compound is one of the ingredients that can produce umami. He went on to successfully build the Ajinomoto Company extracting and marketing this glutamate, which is known to American as monosodium glutamate or MSG.

MSG has become the flavor enhancer of choice for Asian cooks. Contrary to popular belief there is no scientific evidence that MSG produces unhealthy side effects. In fact, MSG in many different guises such as hydrolyzed proteins, autolyzed yeasts and protein concentrates is pervasive in American food products.

Vegetarian Stock Ingredients

Cooks do not have to use an additive to create umami or xian. This flavor is often produced using natural ingredients. The Chinese character for xian (鮮) consists of two parts. The radical on the left is fish (魚) and the other component is lamb (羊). These two ingredients together were believed to be able to create this ultimate xian flavor. It is well known that animal bones are also excellent sources of umami. They are used in both Asian and Western cooking traditions for enhancing stocks.

Selecting vegetarian ingredients full of natural glutamates can also produce excellent umami for stock. Soybeans, mushrooms and corn are all excellent choices. Soybeans need to be rehydrated before use. Choosing to use soybean sprouts, which are readily available in many Chinatown produce markets, makes it easy to include this ingredient. Dried shiitake mushrooms are also full of umami. Add them directly to the pot. They will rehydrate easily as the stock simmers.

So go ahead and make delicious Chinese vegetarian food. Just remember to make sure you use ingredients that will produce lots of umami.
