You wouldn’t write off all cheese after one bite of gorgonzola.
Ricotta, cheddar, cream cheese, halloumi – they’re all made from milk and some form of acid or rennet, but they might as well be different foods entirely. Tofu’s the same story, except most people have only ever encountered one version of it.
A handful of choices – which coagulant you use, what temperature you work at, how much you strain it, what you do to it afterward – take the same base soy milk and turn it into wildly different textures. You get wobbly silken blocks that dissolve on your tongue. You get dense, crumbly slabs you can throw on a grill. You get fried pockets that drink up whatever sauce you put them in. This isn’t one ingredient; it’s an entire category of protein. Once you see how the pieces connect, the tofu aisle will never look the same.
Soy milk and a coagulant start every batch. The coagulant is usually nigari (にがり), which is what’s left after you pull salt from seawater – it’s loaded with minerals. After that, the process splits three ways.
The Three Paths
Kinugoshi dofu (絹ごし豆腐) – silken tofu – gets coagulated right in its container. The curds never get broken up. What you end up with is a continuous gel, smooth from one edge to the other, more like custard than anything resembling cheese. The name translates to “strained through silk,” which describes the texture, not the actual method.
Yosedofu (寄せ豆腐) – gathered tofu – forms when you add coagulant to hot soy milk, let curds develop, then scoop them loosely into a strainer. No pressing, no shaping. The texture stays tender and rustic, and the flavor is nutty and rich. Think fresh ricotta: minimal intervention, maximum expression of what you started with.
Momendofu (木綿豆腐) – cotton tofu – involves breaking up the curds after coagulation and transferring them into a cloth-lined mold. You press it under weight to squeeze out excess liquid. The whey drains through the cotton, which stamps its weave into the surface, and what’s left is denser and more structured. Kinugoshi is panna cotta; momen is paneer.
The Firmness Spectrum
Firmness isn’t the only difference – these different processes create structural differences you can literally see when you slice them open. Within each category, you’ve got a whole range of textures.
At the softest end of silken, the tofu barely holds together. It wobbles on a spoon, dissolves the second it hits your tongue. Top it with a rich, briny crab sauce and it’s tofu at its most luxurious – the warm curds and sauce become one thing as they melt in your mouth. Chill it and serve it as hiyayakko with grated ginger and soy sauce, and it’s one of the best things you can eat when it’s hot outside.
Go a bit firmer and silken tofu starts behaving like a smooth, dense gel you can actually cube. This is where it overlaps with yosedofu and the softer side of momen. It’s the zone where tofu can hold its shape in soup or sauce without losing that tender quality.
I make mapo tofu with this texture. Mapo tofu was actually what turned me onto tofu as a kid, and I think of it more as a template than a set recipe. I’ve made kimchi mapo tofu, and I’ve made something more playful like my taco tofu. That balance between structure and softness is what makes these dishes work.
Keep moving up the scale with momendofu and longer pressing times give you something crumbly and dense. At this level of firmness, you can shave it thin for salads or sear it in a screaming hot pan until it forms a golden crust – tofu steak with tangy sweet Japanese steak sauce and garlic chips.
What Controls the Variation
Beyond the different processes, the coagulant matters. Nigari (magnesium chloride) works fast and pulls out the natural sweetness of the soybeans, but it doesn’t give you much room for error. Hesitate a few seconds and the curds set unevenly. Sumashiko (澄まし粉) – calcium sulfate – coagulates slower and gives you a smoother, more forgiving gel that holds onto more water, which is why commercial silken tofu often uses it.
Then you’ve got the protein content of the soybeans, which changes based on cultivar and growing conditions. You’ve got the mineral content of your water. You’ve got the temperature when you add the coagulant. For momen, pressing time and pressure are your final controls. More of both means firmer and drier tofu. Less means softer and more tender. It sounds straightforward, but with this many variables, two batches made from identical beans on the same day can turn out noticeably different.
I figured this out the hard way making silken tofu at home. Nigari concentration varies all over the place, and soybeans differ in protein, so the right amount is always trial and error. Not enough coagulant and you’ve got a soy milkshake. Too much and the curds seize up, turning grainy and bitter.
Generally, the softer you’re aiming for, the less forgiving the process gets. A good starting point is yosedofu. If you’ve never had it, there’s nothing quite like tofu fresh off the stove.
Making Yosedofu
If you want to try it, soak 120 grams of dried soybeans overnight. Blend them with 2 1/4 US cups of hot water (around 175°F/80°C) until you’ve got something the consistency of wet sand. Squeeze it through a nut milk bag or doubled-up butter muslin into a pot to separate the milk from the pulp. If you’ve squeezed hard enough, you’ll end up with a ball of okara – the fiber-rich soybean pulp – about the size of a lemon.
Soy milk isn’t edible raw, so bring it to a gentle boil, drop the heat, and cook it for about ten minutes, stirring constantly so it doesn’t scald. Strain it once more through a fine-mesh strainer to get rid of the foam.
Dissolve a quarter teaspoon of nigari in two teaspoons of water. Heat the soy milk to 185°F/85°C, add the nigari, and stir gently in a figure-eight about 10 times. Cover the pot and wait ten minutes. When you open it, your soy milk should have turned into curds. Use a slotted spoon to gently move them into a fine-mesh strainer and let them drain for a minute or two. The longer the drain, the firmer the tofu.
I serve fresh yosedofu warm from the pot with something salty. To taste the tofu at its purest, a sprinkle of your favorite finishing salt or my umami seasoning salt is simple and good. A drizzle of dashi soy sauce with katsuobushi flakes, sliced scallions, and grated ginger takes it further.
Secondary Processing
If three families of fresh tofu weren’t enough, deep-frying, grilling, and freeze-drying turn them into even more varieties.
Yakidofu (焼き豆腐) is firm momen with the surface seared until it’s lightly charred. This creates a thick skin that makes it even sturdier. It’s built to hold its shape in a bubbling hotpot, slowly soaking up the broth’s flavor without disintegrating.
Aburaage (油揚げ) starts as thin momen slices, but frying them twice until they puff into hollow golden pockets changes their texture into something almost meaty and gives them a toasty flavor. The best part: they absorb whatever you cook them in. Split them open into little envelopes to stuff with seasoned sushi rice for inari sushi, or use them to top a bowl of kitsune udon.
Atsuage (厚揚げ) is another fried variation using whole tofu blocks fried at higher heat so the outside crisps while the inside stays tender and creamy. Hot from the fryer with a spicy scallion sauce on top, it’s one of the most satisfying ways to eat tofu.
Ganmodoki (がんもどき) uses tofu as an ingredient – you purée it, then mix in shredded vegetables, mushrooms, edamame, and sesame seeds before forming patties and deep frying them. The name literally means “mock goose” because Buddhist monks originally made them as a meat substitute (though calling it similar to goose is generous). I simmer ganmodoki in dashi to load them with flavor, which puts them somewhere between a fritter and a dumpling.
Finally, there’s koya-dofu (高野豆腐), which might be the most dramatic transformation. Centuries ago, a monk on Mount Koya left some tofu outside during winter and forgot about it. The freeze-thaw cycle turned it into something completely new: a spongy, freeze-dried block that could be stored for months. Reconstituted in a flavorful broth, it has a genuinely meaty chew. You can add it to stews, crumble it and use it as a ground meat substitute, or batter it and pan-fry it like a cutlet.
So that’s the universe of tofu – from jiggly custard with an expiration date measured in days to a freeze-dried block that lasts for years. A few months ago I wrote about why tofu deserves better; hopefully this gives you some ideas and inspiration to make your own and turn it into something new.
What’s your favorite style of tofu? If you’ve only tried one kind, which one from this list makes you curious?
