What Is Tofu? Ingredients, Benefits & How to Make It at Home

Tofu has been around for centuries. But here in Canada, it’s only recently become something you see in grocery carts more often. 

If you’re eating more plant-based foods or just looking for a new protein to add to your meals, tofu fits right in. 

That’s why in this guide I’ll break down what tofu is, what it’s made of, and why it’s good for you. I’ll also show you how to make it at home step by step, so you can try it for yourself.

Let’s begin, shall we?

Quick heads up: Making tofu at home might sound like a lot. But if you’ve got the right gear, like a Hurom juicer, it’s much more doable. We’ll get into that later.

What Is Tofu? A Look at Its Origin in Asian Cuisine

Tofu isn’t new. In fact, it’s been part of daily meals across Asia for more than 2,000 years. 

Most agree it began in China, likely during the Han dynasty, when soy milk was curdled into soft solids using natural salts. Some say it was discovered by accident. Others credit Prince Liu An with its invention. 

But like many food origins, the real story is a mix of fact and legend.

There are even a few theories about how it came to be: maybe it was a lucky mix of soy milk and mineral-rich sea salt. Or maybe the technique came from trying to replicate Mongolian milk-curdling methods. 

Either way, by the time the Song dynasty rolled around, tofu was already a common food across China.

As Buddhism spread, so did tofu; mainly because it’s plant-based and full of protein. Over time, each region gave it its own twist:

• China: Seen as a staple, especially during colder months before refrigeration. Tofu was often eaten at family altars for ancestors, since it was soft enough for spirits who’d "lost their jaws."

• Japan: Introduced by monks around the 8th century, tofu became part of Zen temple cooking with Japanese tofu dishes like chilled hiyayakko or fried agedashi.

• Korea: Known as dubu, it’s used in everything from cold sides to spicy stews like soondubu jjigae.

• Vietnam and Indonesia: Tofu is often fried to a golden crisp or simmered in rich tomato or lemongrass broths. Street food favourites like tahu goreng show how flexible it is.

• Southeast Asia: Countries like Malaysia, Thailand, and the Philippines include tofu in both traditional meals and fusion dishes.

Tofu’s real strength is that it adapts, quietly fitting into whatever culture, dish, or style of eating it lands in. 

That’s what helped it make the jump to Western kitchens, too.

Why Tofu Is Popular in Canada Today

Tofu’s no longer just a health food store thing. You’ll find it in grain bowls, stir-fries, soups, and salads across the country, and not just in vegan kitchens. 

More Canadians are choosing plant-based meals, and tofu’s becoming a regular part of the mix.

One reason? It’s easy to access. 

According to Statistics Canada, tofu is already a go-to for many vegetarians and vegans. And since most soybeans in Canada are grown locally (in Quebec, Ontario, and Manitoba), there’s solid access to the main ingredient. 

Some of the biggest growth is happening in cities like Toronto, Vancouver, and Montréal, where multicultural food scenes and flexitarian diets are on the rise.

Speaking of Quebec, tofu producers have seen demand climb sharply. It makes sense; beef consumption has dropped over the past two decades, from 23.23 kg to 16.23 kg per person. 

People still want protein, yes. But they’re looking for something lighter, more sustainable, and easy to work into everyday meals.

And that’s what tofu brings: flexibility. It’s affordable, accessible, and takes on the flavour of whatever you pair it with.

What Is Tofu Made Of?

Tofu might look plain, but what it’s made of is pretty simple, and that’s part of the appeal. Let’s break it down a bit more.

Main Ingredients in Tofu

To make tofu, you just need a few ingredients:

• Soybeans: The base of it all. Most tofu is made from yellow soybeans, soaked and blended to make soy milk. In Canada, soybeans are mainly grown in Ontario, Manitoba, and Quebec, which makes local production possible.

• Water: Used to soak the beans and extract soy milk. The water-to-bean ratio plays a big role in the final texture.

• Coagulants: These are what turn liquid soy milk into tofu curds. Common ones include:

• Nigari (magnesium chloride): A natural salt from seawater, often used in traditional tofu.

• Calcium sulfate: A common and safe option that adds a bit of calcium to the final product.

• Lemon juice or vinegar: More natural alternatives people sometimes use when making tofu at home.

Each coagulant gives the tofu a slightly different texture and taste. That’s why you’ll find so many types, from super silky to extra firm.

Nutritional Value and Health Benefits of Tofu

Tofu is packed with plant-based protein, which is why it’s often used as a meat alternative. But the benefits go well beyond protein:

• It contains all essential amino acids, making it a complete protein.

• It’s rich in calcium, iron, magnesium, and B vitamins like folate and vitamin K.

• It’s low in saturated fat and cholesterol-free.

• It has isoflavones, plant compounds linked to heart health, hormone balance, and possible protection against certain chronic conditions.

Health agencies back this up. The U.S. FDA approved a health claim in 1999 stating that 25g of soy protein a day may help reduce the risk of heart disease. That claim was reaffirmed in 2019 after a review of 46 clinical trials.

Other research highlights how soy isoflavones (found naturally in tofu) can support different aspects of health:

• Heart and cholesterol health: A study out of Pakistan highlighted tofu’s ability to help lower total cholesterol levels. It also pointed to benefits for people managing high blood pressure, type 2 diabetes, and inflammation-related conditions.

• Metabolic and immune function: A review of multiple studies found that soy protein may support better metabolic balance and help regulate immune response. These effects are tied to both protein quality and isoflavone content.

• Inflammation and chronic disease risk: Studies in Japan have shown that soy isoflavones may lower inflammation markers, particularly in people at risk for chronic diseases. 

• Cancer risk reduction: A study from China found that higher intake of soy and isoflavones was linked to a lower risk of several types of cancer, with particularly strong associations for lung and prostate cancer. The researchers noted that this protective effect seemed especially tied to isoflavones.

So yes, simple ingredients and real impact. Tofu’s not just a meat replacement. Actually, it’s a nutrient-dense food with strong science behind it.

Pro Tip: Thanks to its iron content, tofu can be a good ally when you need more of that mineral in your diet. Pair it with iron-rich juices, like these juices for anemia.

Types of Tofu and Their Culinary Uses

Not all tofu is the same. Its texture can range from super soft to really firm, and each type works better in certain dishes. 

Once you know the difference, it’s easier to use tofu in a way that fits what you’re cooking.

Here’s a quick guide to the main types and how to use them:

Silken Tofu

This is the softest version; smooth, creamy, and high in water content. It’s typically used in:

• Smoothies: It adds protein without affecting the taste or texture too much.

• Sauces and dips: Great for blending into creamy dressings or spreads.

• Desserts: Works surprisingly well in things like vegan cheesecakes or chocolate mousse.

You’ll usually find it in vacuum-packed containers, and it’s more delicate than other types, so handle it gently.

Soft and Medium Tofu

These fall somewhere between silken and firm tofu. They hold their shape a bit more but are still quite tender. Good uses include:

• Soups: Classic in miso soup and hot & sour soup, where it adds body without overpowering the broth.

• Steamed dishes: Soaks up flavour while staying soft and mild.

• Light sautéing: Can be gently cooked, though it’s not ideal for grilling or baking.

If a recipe calls for “regular tofu” without more detail, soft or medium tofu is usually a safe bet.

Firm and Extra-Firm Tofu

This is the go-to for hearty meals and dishes where tofu needs to hold its shape. It’s:

• Easy to cube, slice, or crumble.

• Great for grilling, stir-frying, or baking.

• Ideal for marinated tofu or anything crispy on the outside and tender inside, like black pepper tofu or Hoisin tofu noodles.

Pro Tip: Pressing it before cooking helps remove excess water and improves texture. Some brands sell it pre-pressed, but if not, a tofu press (or just a heavy pan and paper towels) does the job.

How to Make Tofu at Home

If you’ve ever looked at a block of tofu and wondered how it’s made, the process is surprisingly doable. Especially if you like working with simple ingredients and don’t mind getting your hands a bit messy. 

You’ve got two main options. Both give you fresh tofu, and you get full control over the texture and flavour. Let’s meet them:

Traditional Method

Making tofu from scratch takes a bit of time and a few tools, but the process is pretty straightforward once you get the hang of it.

Here’s how it works:

1. Soak soybeans overnight in plenty of water. They’ll expand to about double or triple their size.

2. Grind the beans with fresh water to make soy milk. A blender works fine for this step.

3. Cook the soy milk in a saucepan, stirring constantly to keep it from burning.

4. Strain out the pulp (called okara) using a fine mesh strainer or cheesecloth. What you keep is the soy milk.

5. Add a coagulant (like nigari, calcium sulphate, or lemon juice) to the hot soy milk and stir gently until curds form.

6. Transfer the soy curds to a tofu mould lined with cheesecloth, press them to remove liquid, and let them set.

This way, you’ll get a block of fresh tofu you made from scratch. 

The downside? It takes time, and clean-up can get messy, especially when straining and pressing by hand.

How to Make Tofu with a Cold-Pressed Juicer (Hurom Method)

If you’ve got a cold-pressed juicer, like a Hurom model, it cuts the process down a lot. There’s no need to grind the soybeans yourself or deal with straining hot milk over the sink.

Here’s how I usually do it:

1. Soak 300g of soybeans in water for a full day.

2. Assemble your juicer. Keep the juice cap and the pulp lever closed.

3. Add soaked beans and filtered water in a 1:1 ratio into the juicer to extract fresh soy milk. 

Pro Tip: Tofu doesn’t have to be plain white. Add chopped spinach, carrot, or celery at this stage for a pop of colour and a fun change in flavour.

4. Open the pulp lever halfway toward the end to release compressed soy pulp (okara).

5. Boil the extracted soy milk in a pot, stirring gently to prevent sticking.

6. Add your coagulant (like natural bittern or a vinegar-salt mix) slowly while stirring. You’ll see the curds begin to separate.

7. Pour into a tofu press and press to your desired firmness.

Compared to the traditional method, this one saves time, cleanup, and effort. And you still get that satisfying feeling of making something from scratch.

Ways to Use Homemade Tofu in Everyday Cooking

Once you’ve made your own tofu, it’s good to know that you don’t need fancy recipes to use it. Tofu plays well with almost anything, and it can take on whatever flavour you give it. 

Just take a look at the ideas below.

Simple Meal Ideas

Here are some go-to ways I like to use tofu during the week:

• Stir-fries with vegetables and tofu: A classic. Use firm or extra-firm tofu, pan-fry it until golden, then toss it in with your favourite veggies and a splash of soy sauce or tandoori paste.

• Grain bowls with baked or marinated tofu: Tofu works great in quinoa or rice bowls. Press it, cube it, marinate it (soy sauce, garlic, sesame oil, done), then bake until crisp.

• Salads topped with crispy tofu: Breaded or air-fried tofu makes a satisfying, crunchy topping.

• Hot & sour soup: Soft or medium tofu gives body and protein to this classic Asian-inspired dish.

• Black pepper tofu: A bold, savoury dish with caramelized onions and cracked black pepper. It’s a must-try if you like big flavour.

Each one of these is quick to prep and easy to adjust depending on what you’ve got in your fridge. Tofu’s flexibility is part of what makes it so practical.

Creative Recipes with Tofu

If you want to take things a step further, tofu also works in more unexpected ways. Some of my favourites:

• Smoothies with silken tofu: A few cubes of silken tofu make your smoothie extra creamy without needing yogurt or protein powder.

• Creamy sauces and soups: Blend silken tofu into pasta sauces, miso soup, or even use it as a base for vegan alfredo.

• Black bean tofu: Marinate tofu in a black bean garlic sauce for a rich, umami-packed dish.

• Hoisin tofu noodles: Toss tofu with hoisin sauce and noodles for a quick weeknight fix.

• Fermented tofu or fermented bean curd: Great for adding depth to broths, marinades, or used sparingly as a condiment.

• Dried tofu: Use in stir-fries or shred into noodle bowls for a chewier bite.

• Smoked tofu: Adds a savoury note to sandwiches, wraps, or breakfast scrambles.

• Velvety vegan chocolate mousse: Silken tofu + melted dark chocolate + a splash of maple syrup = surprisingly indulgent dessert.

Pro Tip: If you’ve never tried marinating tofu ahead of time, give it a go. It makes a big difference in both flavour and texture. Even a 30-minute soak in something like tamari, ginger, and lime can turn a plain block into something crave-worthy.

Ready to Try Tofu for Yourself?

Tofu might seem simple, but once you know what it’s made of and how to use it, it opens up a whole new set of possibilities in the kitchen. 

It’s made from simple ingredients, but the result is a versatile, protein-rich food that fits into almost any meal. And making it at home isn’t as complicated as it sounds, especially if you use a cold-pressed juicer like Hurom to speed things up and keep cleanup low.

So next time you’re planning meals for the week, maybe give tofu a spot on your plate. It might surprise you how well it fits.

FAQs
