What is Stinky Tofu: Comprehensive Guide for the Curious Foodie

What is Stinky Tofu?

Stinky tofu, a popular food item in China, Indonesia, and Taiwan, is a type of fermented tofu known for its strong odor. Traditionally, nighttime markets and roadside stands sell it as a snack or side dish, while it isn’t as common in restaurants (source).

This unique tofu variation goes through a fermentation process involving a brine made from a variety of ingredients such as rotted vegetables, shrimp, fermented milk, various meats, and Chinese herbs (source). To create stinky tofu, the tofu is marinated in a fermented broth, usually for 4-6 hours. During this time, enzymes present in the broth break down the proteins in the tofu, releasing compounds like hydrogen sulfide and ammonia, which contribute to its characteristic smell (source).

The fermentation broth used for stinky tofu can take months to develop, but the resulting stinky tofu can vary in flavor and stinkiness depending on the geographical location and local preferences in China as well as other parts of the world (source). A simpler method of making stinky tofu involves mixing mashed stinky tofu with cold water, adding a small amount of white wine vinegar or baijiu spirit, and marinating regular tofu cubes in the mixture for 24 hours or more (source).

Despite its pungent odor, stinky tofu has many fans who enjoy the taste and unique experience it offers. The burst of flavors and the contrast between its crispy exterior and soft interior make it a sought-after delicacy. Keep in mind that stinky tofu, like other fermented bean curd dishes, can be an acquired taste, and newcomers may need some time to adjust to its distinct smell and flavor.

History and Origin

Stinky tofu, a traditional Chinese delicacy, has its roots in the southeastern maritime areas of China. Its origin can be traced back to the Qing dynasty, when a tofu vendor named Wang Zhi He is said to have accidentally invented this unique dish. He had a surplus of unsold tofu, so he decided to cut it into small cubes and stored it in a jar for several days. To his surprise, the tofu fermented and turned a greenish color, resulting in the creation of stinky tofu¹.

While there is another version of the story claiming that a monk named Zhu Yuanzhang first tasted stinky tofu in a moment of intense hunger, it is more widely accepted that the dish has its origins in China during the Qing dynasty². From China, stinky tofu spread across the region and gained popularity in several East and Southeast Asian countries, including Taiwan, where it became a popular street food item.

The key element in making stinky tofu is the fermented brine in which the tofu is soaked³. Traditionally, this brine is made from a combination of fermented milk, vegetables, and meat. Other ingredients that might be added to the mix include dried shrimp and amaranth³. Fermented bean curd, another essential component, is made from soybeans that are soaked and turned into a soft, flavorful food product⁴.

In the preparation of stinky tofu, the tofu is first marinated in the fermented brine, absorbing the flavors and taking on its characteristic pungent aroma³. The tofu is then usually deep-fried, grilled, or steamed, and served with accompaniments such as garlic, chili sauce, or soy sauce. The dish is known for its strong smell, which has been described as similar to rotten garbage or smelly feet. Despite the off-putting scent, stinky tofu is enjoyed by many for its unique taste and texture.

Stinky tofu can be found in various forms in different countries:

• In Taiwan, you may find it served as a snack in night markets, often deep-fried and accompanied by pickled cabbage and chili sauce³.
• In mainland China, it is common to encounter stinky tofu sold by street vendors, who sometimes offer it in steamed, braised, or boiled form¹.
• In Hong Kong, stinky tofu is typically served in small pieces, deep-fried and topped with sweet sauce, chili, and garlic.

In closing, stinky tofu is a popular and widely enjoyed dish with a rich history dating back to the Qing dynasty of China. Its unique flavor and aroma are the result of the fermented brine, fermented bean curd, and various ingredients, such as dried shrimp and garlic, that contribute to its unmistakable character³⁴.

Ingredients and Preparation

Basic Ingredients

Stinky tofu, a popular Chinese snack known for its strong odor, starts with a simple base: firm tofu. The tofu undergoes a fermentation process that accounts for its distinctive smell and taste. A crucial component of this process is the brine, which usually consists of fermented milk, vegetables, meat, and fish. Some variations may include shrimp, amaranth greens, mustard greens, bamboo shoots, or Chinese herbs. The duration of fermentation varies, ranging from a few weeks to several months, depending on personal preference for potency¹².

Flavoring and Spices

Once the tofu has been prepared and fermented, it is typically cooked and served with a variety of flavorings and spices. Some popular additions include:

These ingredients can either be incorporated into the brine or added during the cooking process to enhance the stinky tofu’s taste. Additionally, the dish is often custom-made for a preferred level of spiciness or sweetness.

Fermentation Process

The fermentation process is what gives stinky tofu its unique, pungent aroma. Starter bacteria play a vital role in initiating the fermentation². Enzymes present in the broth break down the proteins in the tofu, releasing compounds such as hydrogen sulfide and ammonia, responsible for the stinky smell⁴. The tofu is typically marinated in the fermentation broth for 4-6 hours before serving.

The flavor and potency of stinky tofu may vary, depending on the ingredients used in the fermentation process or the brine’s specific recipe. This distinctive snack, rich in taste and history, is a unique culinary experience and, for many, an acquired taste.

Cooking Techniques

Deep Frying

Stinky tofu, known as chou doufu, is a popular food mainly found in China, Taiwan, and Indonesia. It gets its name from the unique fermentation process that gives it its strong smell, often compared to blue cheese or rotting garbage (source). A favorite technique for preparing stinky tofu is deep frying. To prepare, the tofu should first be marinated in a brine made from fermented milk, vegetables, meats, or shrimp for a minimum of 24 hours to attain the desired level of stinkiness (source).

When deep frying, it is essential to ensure the oil reaches an appropriate temperature, usually around 350°F (175°C). This allows the tofu to develop a crispy exterior while maintaining its signature soft texture inside. The process of frying releases additional aroma compounds, which further enhances the distinct smell of stinky tofu. It is typically served with dipping sauces such as soy sauce or chili paste to complement the strong flavors.

Boiling

Another method of cooking stinky tofu involves boiling or steaming it. This technique is often used in soups and hot pot dishes, where the tofu absorbs the flavors from the broth while maintaining its signature scent and taste (source).

When boiling, the key is to place the marinated stinky tofu in simmering water or broth for a few minutes, just long enough for the tofu to heat through without becoming too soft or losing its distinct taste. This method often results in a more delicate texture compared to deep frying, as it gently cooks the tofu without the addition of excess oil.

In conclusion, stinky tofu can be enjoyed through various cooking techniques such as deep frying and boiling. Both methods showcase the unique and robust flavors of this dish. It is essential to marinate the tofu properly and consider the desired texture and presentation when choosing the cooking technique.
