Fermented Tofu

Posted by Joeline Degenaar on November 25, 2024

If you’ve ever enjoyed the savoury, complex notes of fermented foods, fermented tofu is a must-try. This creamy, umami-packed ingredient has been a beloved staple in many Asian cuisines for centuries, celebrated for its rich flavour and versatility in cooking. By fermenting tofu at home, you can create a gourmet condiment that enhances your meals with a depth of flavour that store-bought versions can’t match.

What is Fermented Tofu?

Fermented tofu, also known as doufu ru or fu ru in Chinese, is a traditional food made by preserving tofu cubes in a salty brine until they develop a creamy, spreadable texture and an intensely savoury flavour. Often referred to as “Chinese cheese” due to its soft, cheese-like consistency, fermented tofu can be mild or bold, depending on the spices and fermentation time used. This delicacy is commonly enjoyed as a condiment, marinade, or flavour enhancer in dishes like congee, stir-fries, and soups. Its unique taste—a perfect balance of saltiness, creaminess, and tanginess—makes it a favourite for food enthusiasts and adventurous eaters alike.

A Brief History of Fermented Tofu

The origins of fermented tofu date back thousands of years in China, where it was first developed as a method of preserving tofu for longer storage. Over time, it became a valued culinary ingredient, spreading to other parts of Asia, including Japan, Korea, and Vietnam.

Different regions put their own spin on fermented tofu. For example:

Chinese-style fermented tofu often includes rice wine, chillies, and spices for a bold flavour.

Japanese-style miso-aged tofu combines tofu with miso paste for an extra layer of umami.

Southeast Asian variations might incorporate garlic or shrimp paste for unique twists.

Today, fermented tofu is celebrated for its ability to elevate simple dishes and its impressive shelf life, making it a pantry essential in many households.

Why Make Fermented Tofu at Home?

Homemade fermented tofu is not only rewarding but also allows you to customise the flavours to suit your preferences. Here’s why you’ll love it:

Unparalleled Freshness: Store-bought versions can’t compete with the depth of flavour and creaminess of homemade tofu.

Customisable Flavour: Adjust the spice level or add unique ingredients like star anise, garlic, or herbs for a personalised touch.

Nutritional Benefits: Fermented tofu is packed with probiotics that support gut health, along with plant-based protein, calcium, and iron.

Eco-Friendly: Making your own tofu reduces packaging waste and allows you to control ingredient quality.

Tips for Perfect Fermentation

To ensure your fermented tofu is a success, follow these helpful tips:

Start with Quality Tofu: Firm or extra-firm tofu works best, as it holds up during the fermentation process. Opt for organic tofu if available.

Sterilise Equipment: Clean jars and utensils thoroughly to prevent contamination and ensure a safe fermentation process.

Control Temperature: Keep the jar in a cool, dark place for consistent fermentation. If it’s too warm, the tofu may ferment too quickly or unevenly.

Be Patient: The flavour intensifies with time, so let the tofu ferment longer if you prefer a bolder taste.

Creative Ways to Use Fermented Tofu

Fermented tofu’s creamy texture and umami flavour make it a versatile ingredient. Here are some ideas to inspire you:

Spreads: Mash it onto toast or crackers for a savoury snack.

Marinades: Blend it with soy sauce, garlic, and sesame oil for a rich marinade for vegetables or proteins.

Soups: Stir a cube into soups or broths for an instant flavour boost.

Rice Dishes: Pair it with steamed rice, congee, or fried rice for a classic Asian-inspired meal.

Dips: Mix it with tahini or yoghurt to create a creamy, umami-packed dip.

How to make Fermented Tofu at Home

Ingredients:

450g firm tofu (organic, if possible)

2-3 tbsp sea salt

1/2 cup rice wine or vodka

1 tsp peppercorns (optional for added flavour)

2-3 dried chillies (optional)

2-3 tbsp miso paste (optional for extra umami)

Instructions:

Prepare the Tofu: Drain and press the tofu for about 30 minutes to remove excess water. Once pressed, cut it into 2.5 cm cubes. This step ensures the tofu absorbs the brine effectively.

Dry and Salt: Coat each tofu cube evenly with sea salt and place them on a clean tray. Cover with a cloth and let the tofu sit at room temperature for 24-48 hours. As it dries, the tofu becomes firmer, readying it for fermentation.

Make the Brine: In a sterilised jar, mix the rice wine (or vodka), peppercorns, dried chillies, and miso (if using). This brine is essential for adding depth and preserving your tofu.

Ferment: Once the tofu has dried, place the cubes into the jar, ensuring they are fully submerged in the brine. Seal the jar tightly and store it in a cool, dark place for 1-2 weeks to ferment. The longer it ferments, the deeper the flavour develops.

Ready to Enjoy: When the tofu reaches your desired flavour, it’s ready to eat! Serve it with rice, stir it into soups, or spread it on toast for a burst of umami. Refrigerate once opened to maintain its freshness.
