Fermented Tofu

by Tiana Matson

Fermented tofu is yet another major condiment in the Chinese cuisine. It’s easier to compare the fermented tofu to the western cheese because of its funk and runny consistency. Some people also call it the Chinese cheese because it has a stinky smell but an amazing taste.

Fermented Tofu

Before we learn more about fermented tofu, what is tofu?

It is also known as bean curd. This Chinese native product is some food that is made from condensed milk that is pressed into solid white blocks. Its processing is quite similar to the way cheese is made.

WHAT IS FERMENTED TOFU?

Fermented Tofu

It is a Chinese salty condiment that is made from preserved tofu. It is used in all the parts of China and a few neighboring Asian countries like Taiwan and other major cities where you find the Chinese. It’s also known as fermented bean curd, tofu cheese, soy cheese or preserved tofu.

The fermented tofu is made using soybeans, salt, water, vinegar, sesame oil and rice wine. Note that the fermented tofu has a soft and spreadable texture as well as savory taste that resembles cheese.

THE HISTORY OF FERMENTED TOFU DEVELOPMENT

It is believed that the fermented tofu originated in China but the exact date and time of origin is uncertain. An author by the name Wai discovered writings about the same from a food encyclopedia indicating that another author by the name Wang Su in 1861 had noted that the firm tofu which is today known as fermented tofu was not suitable for children.

Nonetheless, he stated that the tofu was important for the sick. These writings made Wai state that fermented tofu must have existed prior to the Ching dynasty (1662-1912). There is no proper documentation but we believe that it’s during Ching’s dynasty that the fermented tofu started to spread in East Asia.

Note that fermented tofu is not so common in Japan as it is in China.

THE PRODUCTION METHOD

If you are familiar with the cheese production method then note that this is not quite different. The production of fermented tofu happens when molds are introduced to the tofu then you let them grow for a few days.

Next, make a brine solution that contains: rice wine, vinegar, chili pepper, cinnamon, star anise, red yeast rice(optional) and ginger. Then take your fermented tofu and soak in this solution. Let it marinate for either weeks/months or a year.

You just need to keep observing to ensure that the tofu has hardened in consistency and that it has the savory flavor you need. Whenever you need to taste the fermented tofu’s flavor, just spread it on the bun then eat it.

Note that, the preparation method varies from one region to another and the type of tofu you are making although the basic steps are:

  • Preparation of the tofu
  • Molding or the first fermentation process
  • Brining or the second fermentation process.

THE VARIETIES OF FERMENTED TOFU

There are many varieties as listed below

White fermented tofu: the variety is made using soybean, water, alcohol, sesame oil and calcium sulfate. You can alter the flavor, aroma and color using a different kind of spices,

Red fermented tofu: you can make it using the above similar ingredients with the addition of red rice yeast and wine. When you combine the red rice yeast with the brining color you will get the very deep color.

Stinky fermented tofu: its fermentation takes place for more than 6 months. It has a strong creamy flavor with a strong smell.

Chiang fermented tofu: this is made using tofu that is soaked in Chinese miso or soy sauce for a number of days. It assumes the reddish-brown color.

THE BASIC TYPES OF TOFU

  • Tofu molded before picking

This is by far the most common tofu in the market today. It is the kind of tofu that is formed from the process I described above. The process involves the first fermentation and the second fermentation process.

  • Molded tofu fermented with brine or salt

This is the kind that is prepared without wine or alcohol. They are tofu cubes that are fermented in brine or kept in salt

  • Molded tofu with red or white koji

Here the molded tofu is made and during the fermentation, there is an addition of rice koji/hung chu for flavor and color. It’s also used to add a second source of enzymes. The other difference is that you reduce the amount of water during fermentation.

  • Molded tofu fermented in rice wine or its lees

This is prepared without the use of salt. You ferment the cubes in rice wine for about 12 hours and then later in its lees and in some places, they may use cloves, orange peels, crushed leaves and green mucor.

  • Molded tofu pickled in soy sauce or miso

Here, you sprinkle salt to the molded tofu then immerse in soy sauce or miso.

TOFU THAT IS NOT MOLDED BEFORE FERMENTATION

  • Tofu pickled in soy sauce or miso:Firm tofu is drained and sprinkled with salt then immersed in soy sauce
  • Dried tofu is fermented with millet brandy plus red and white koji:You prepare by cutting firm tofu then immerse in ground red and white koji.
  • Firm tofu fermented with wheat koji and brining liquor
  • Firm tofu and wine fermentation
  • Tofu fermented with brine and salt

USES OF FERMENTED TOFU

  • Culinary uses

This common Asian delicacy acts as a condiment to various dishes, you could combine it into sauces or use it to flavor your breakfast meals. These meals may include porridge or rice. It could work as an ingredient to your dipping sauce.

Some people use it for braised meats, stir-frying and steamed dishes. You could serve it with your steamed buns or noodles. Nevertheless, note that the red and white tofu own different flavors which are distinctly unique.

  • Nutritional value

This being a soy product can convert minerals like calcium magnesium, iron, potassium, zinc and copper to more soluble forms. Moreover, the fermented product increases the vitamins and minerals amounts in your body.

  • Medicinal benefits

This product could help reduce cholesterol level and act as a protective agent against some cancers. It enhances the intestinal health as well as digestive tract health.

The fermented soy product also increases the hyaluronic acid which lubricates your joints and reduces the tendency for arthritis associated inflammations. Generally, this increases your bone strength while promoting the heart health.

Characteristic of fermented tofu

I would associate this with some dairy products. This is because when you put it in your mouth, you feel the same way as the cheese among other products. The characteristic is attributed to the fact that during fermentation and air-drying process, the proteins are broken down the same way as it happens in cheese products.

The fermented tofu has a strong aroma and flavor which is taken from the marinades. It is said to be salty with some hint of mild sweetness.

It has a firm, smooth paste-like taste and texture when in the mouth.

When refrigerated, the fermented tofu can be kept for a long time/for years and its flavor is believed to improve during this time.
