What is tofu? What is it made of? How do you cook it? What are the different variations? All your tofu questions can be answered here!

What is tofu?
Most people know that tofu is a soy-based something, and until recently, I fell into this category. Not really sure what this mystery block of white mush actually was.
But it’s actually really neat! The making of tofu parallels the making of cheese. With cheese, you take milk and add rennet or an acid, causing the casein proteins in the milk to aggregate into clumps.
With tofu, you take soymilk and add calcium sulfate, causing similar clumping. Then you just take these coagulated clumps and press them together into the classic tofu cube! The amount of water pressed from the cube determines the firmness of the tofu.
Where to buy tofu
Look for tofu in the produce, refrigerator, or vegetarian section of most groceries. Pro tip: You can often find cheaper, fresher tofu at Asian groceries!
Variations of tofu
There are two main varieties of tofu: silken and regular. Silken tofu has a much silkier texture and originated in Japan. Original tofu is more common and was first made in China. Each of these tofu varieties can vary in firmness:
- Soft Tofu: Very versatile, is often substituted for dairy and eggs in desserts.
- Firm Tofu: Firm enough to pan fry, but can also be crumbled (like to replace scrambled eggs).
- Extra Firm Tofu: The most dense variety, well suited for cutting into cubes and baking or frying, but the high density means less flavors are absorbed.
There is also a variety called “sprouted” tofu. While most tofu is made with the whole soybean, sprouted tofu is made with a sprouting bean. It has more protein, but can be pretty hard to find.
How to Store Tofu
Tofu can either be stored in the refrigerator or the freezer. To store in the fridge, keep fresh tofu in the water it comes in. Every few days, replace the water with fresh water.
To store fresh tofu in the freezer, place entire (unopened) container in freezer. When you’re ready to use it, let it thaw in the fridge for a few hours, then drain the water and squeeze additional water from the tofu. Freezing adds texture and creates a more durable, less crumbly tofu (though I’d only suggest freezing the firm tofu).

How does shelf-stable tofu compare to the types you generally find in the produce section of the market?

They can be used interchangeably! You’ll often find silken tofu packaged this way.
