Selecting the Right Tofu

The first thing you will need is a good quality tofu. It is important to choose a tofu that is firm and has a high protein content, as this will help to ensure that it ferments properly. You can use either fresh or frozen tofu, but it is important to make sure that it is not too soft or watery.

Choosing Molds and Bacteria

Additional Flavouring Agents

In addition to the tofu and mold, you will also need some additional flavouring agents to give your fermented tofu its unique taste. Some common ingredients include salt, tea, sugar, sesame oil, garlic, soy sauce, spices, ginger, and star anise.

The Fermentation Process

If you're a fan of Chinese cuisine, you've probably come across fermented tofu, which is also known as chao. Fermented tofu is a condiment that is cheesy and tangy in flavour. It can be used to add plenty of flavour to soups, marinades, dipping sauces, and more! In this section, we'll go through the fermentation process of making this delicious condiment.

Preparing the Tofu

To make fermented tofu, you'll need to start with a block of firm tofu. Rinse off the tofu and dry the surface with a kitchen towel. Cut the tofu into cubes and place them on a paper towel to dry for a few hours. Once the cubes are dry, submerge them in a mixture of salt and water for a few hours. Rinse the cubes and dry them again.

Culturing and Fermenting

Place the tofu cubes in a jar and cover them with a brine made from water, salt, and your choice of spices. You can use a variety of spices such as chilli flakes, Sichuan peppercorns, or garlic. Make sure the cubes are completely submerged in the brine. Cover the jar with a lid and store it in a dark place for a few days.

During this time, molds will start to grow on the surface of the tofu. This is a natural part of the fermentation process. You can scoop off any molds that appear on the surface of the brine. However, if the molds appear on the tofu cubes, you'll need to discard them as they can cause contamination.

Storing Fermented Tofu

Once the tofu has fermented to your desired taste, you can store it in the refrigerator. Place the tofu cubes in a clean jar and cover them with the brine. You can also add a piece of kombu or a few drops of vinegar to the brine to help preserve the tofu. Store the jar in the fridge for up to a month.

If you want to add a seafood twist to your fermented tofu, you can try adding some dried shrimp or scallops to the brine. The seafood will add a unique umami flavour to the tofu. However, make sure to use dried seafood as fresh seafood can cause contamination.

Avoiding Common Mistakes

Making homemade Chinese fermented tofu may seem intimidating at first, but with a few tips and tricks, you can avoid common mistakes and achieve a creamy, salty, and umami flavour that is sure to impress.

One common mistake is not removing excess water from the tofu before fermenting it. To avoid this, place the tofu on a paper towel and roll it gently to absorb the excess water. Another mistake is not using a heavy object to press the tofu down while it ferments, which can result in a less creamy texture. To fix this, place a heavy object on top of the tofu, such as a can or a jar, to compress it.

It is also important to keep an eye out for black mold, which can occur if the tofu is not properly sterilized. To avoid this, make sure to sterilize all equipment before use and keep the tofu in a clean and dry environment while it ferments.

Enhancing Flavour and Texture

To enhance the flavour and texture of your homemade Chinese fermented tofu, try adding seafood to the recipe. Seafood such as shrimp or scallops can add a sweet and cheesy flavour that pairs well with the salty and tangy taste of the fermented tofu.

To achieve a creamier texture, use a higher fat content tofu or add a small amount of cream to the brine. You can also experiment with different spices and herbs, such as Sichuan peppercorns or garlic, to add depth and complexity to the flavour.

In the summer months, consider fermenting your tofu at a slightly lower temperature, around 25°C, to prevent the brine from becoming too sour. And lastly, don't be afraid to experiment and adjust the recipe to your liking. With a little practice and patience, you can create a homemade Chinese fermented tofu that is sure to impress.
