Tofu Water: Does It Evaporate During Cooking?

Tofu is a versatile ingredient that can be prepared in a variety of ways, including steaming. Steaming tofu is a popular method, especially in East Asian countries, as it helps to remove moisture and improve the texture, making it silkier and less watery. It also helps to get rid of the raw soybean taste, giving it a cleaner flavour.

When steaming tofu, it is important to start with a block of soft or silken tofu. The tofu is then cut into slices or cubes and placed in a steamer basket or on a plate over simmering water. It is typically steamed for around 6 to 10 minutes, depending on the desired texture.

After steaming, the tofu can be seasoned or served with a sauce, such as a soy garlic sauce or a spicy Hunan sauce. It can be served as a hot appetiser, a light main dish, or as a side.

Boiling tofu reduces moisture and improves texture

Boiling tofu is a common practice in Chinese and East Asian cooking. The process involves adding tofu to salted hot water for a short period, usually 5-10 minutes, and then removing it to drain and dry. This technique is used to improve the texture and flavour of tofu and is often done before frying or baking.

Reducing Moisture

Boiling tofu in salted water helps to reduce moisture by drawing out excess water from the bean curd. The heat causes the innermost liquid to move towards the surface of the tofu, which can then be blotted off with a kitchen towel or left to steam dry. This step is particularly important if you plan to fry the tofu, as a dry surface is crucial for achieving a crispy texture.

Improving Texture

The process of boiling tofu also improves its texture by making it firmer and more structurally sound. This added firmness allows the tofu to withstand more vigorous cooking methods such as long simmering and frying without falling apart. The heat from the boiling water tightens up the protein structure, resulting in a tofu that is bouncy and supple.

Enhancing Flavour

In addition to improving texture, boiling tofu in salted water also enhances its flavour. The salt infuses the tofu with a delicate briny taste. For tofu that will be used in braised dishes or stews, unsalted water can be used instead to allow the tofu to absorb the flavours of the dish during cooking.

Alternative Methods

While boiling is an effective method for reducing moisture and improving texture, it is not the only way to prepare tofu. Steaming tofu is another popular method, particularly for silken tofu, as it preserves the soft and slippery texture while infusing it with the flavours of the steaming liquid. Marinating tofu, on the other hand, is generally considered less effective as tofu is a dense substance that does not easily absorb flavours unless it has been previously frozen or defrosted.

Tofu is a versatile ingredient

Tofu is available in varying textures, from silken to extra-firm. The right texture should be selected depending on the dish. For example, soft silken tofu is suitable for blending into desserts or slicing into miso soup, whereas extra-firm tofu is needed for serving it as a main dish or topping. Tofu contains a lot of water, and it is recommended to squeeze most of it out, especially if baking, grilling, or frying.

Tofu is also used in many East Asian and Southeast Asian cuisines. In modern Western cooking, it is often used as a meat substitute. It is a traditional component of many East Asian cuisines, such as Chinese, Japanese, and Korean. Tofu was introduced to Japan by Zen Buddhist monks, who initially called it "Chinese curd". In Southeast Asia, tofu was introduced by Chinese immigrants from Fujian province. Tofu is widely available and used in many local dishes in Indonesia, Malaysia, Singapore, Thailand, Cambodia, Myanmar, the Philippines, and Vietnam.

Tofu is a nutrient-dense food that is high in protein and contains all the essential amino acids the body needs. It is also a good source of calcium, manganese, copper, selenium, vitamin A, phosphorus, and magnesium. It is low in calories and can be used as a cholesterol-lowering food. It may also help reduce the risk of certain cancers, type 2 diabetes, and heart disease.

Tofu can be frozen to change its structure

Freezing tofu is a great way to improve its texture and make it chewier and meatier. When tofu is frozen, the water in it expands, destroying the original structure. This leaves behind little holes, which make the tofu more porous and spongy. This new structure makes the tofu stronger and firmer, and it also gains a more pleasant mouthfeel.

The holes in frozen tofu are also perfect pockets for absorbing and storing flavour. Like a sponge, frozen tofu is excellent at soaking up sauces and broths. Marinating tofu can be difficult as the marinades struggle to penetrate the interior. However, freezing tofu first makes it much more efficient, as the tofu becomes more porous and can better absorb the flavours.

Freezing tofu is also a great way to make it last longer. While tofu lasts for weeks unopened in the fridge, it will last for much longer in the freezer.

To freeze tofu, simply cut whole blocks of tofu into whatever size you plan on using. Then, place them on a sheet tray or in a freezer-safe container or bag. If you don't plan on using all the tofu at once, separate it into portions so you can defrost one helping at a time. The tofu will be frozen solid in about 4-6 hours. You can then either throw the tofu directly into what you're cooking or thaw it first, depending on your preferences and the recipe.

Tofu is a popular Chinese ingredient

Tofu is a traditional component of many East Asian and Southeast Asian cuisines. In modern Western cooking, it is often used as a meat substitute. Tofu has very little flavour or smell of its own, so it can be used in both savoury and sweet dishes, acting as a bland background for the other ingredients.

In East Asian cooking, tofu is prepared in many ways, including raw, stewed, stir-fried, in soup, cooked in sauce, or stuffed with fillings. Many Chinese tofu dishes may include meat. Tofu is also commonly grilled, fried, or steamed.

• Pressed tofu (dougan): This is a category of extra firm tofu that is pressed very dry and then smoked, stewed, or salted. It is eaten in most major regions of China in stir-fries, dumpling fillings, and grilled dishes.
• Yuba (youdoupi): Yuba is the high-protein film that collects on top of heated soy milk. It is eaten as sheets or rolled into "tofu sticks" (fuzhu). Yuba sheets are often used as a wrap for other fillings and then fried and/or steamed. They are widely eaten throughout China.
• Tofu sheets (qianzhang): Qianzhang are cardstock-thin sheets of ground and then pressed soy curds. They are the most protein-dense tofu due to their minimal moisture content and are commonly eaten sliced in cold salads. They are especially popular in China's northeast region.
• Spongy tofu (qianye): This is a special type of tofu made directly from soy protein, not whole beans. It has a tender, chewy, and fishcake-like texture. Spongy tofu is usually stir-fried but can also be grilled or baked and is most common in northern China.
• Fermented tofu (furu): This is an extremely umami-rich tofu made by fermenting cubes of firm tofu with spices, alcohol, and seasonings. It can develop notes ranging from provolone to blue cheese and is usually eaten as an accompaniment to other foods.

Tofu can be used in sweet dishes

Tofu is a staple in many kitchens and is a great meat alternative. It can be used in savoury dishes, but it can also be used in sweet dishes.

For example, silken tofu can be used as a substitute for fish in a Cantonese-style steamed tofu dish. The tofu is seasoned with a little salt and white pepper, and then steamed. A sauce made from ginger, scallions, cilantro, and sweet soy sauce is then poured over the tofu.

Tofu can also be used to make a sweet and sour dish. The tofu is marinated in a mixture of soy sauce and apple cider vinegar, coated in cornstarch, and then fried until crispy. The sauce is made from sugar, tomato paste, vinegar, soy sauce, and water. This dish is often served with sesame seeds and scallions as a garnish.

Another option for a sweet dish using tofu is to steam it and serve it with a soy garlic sauce. The sauce is made from garlic, black vinegar, vegetarian oyster sauce, sugar, and chili oil. This dish can be served as a hearty side or starter, or with rice, congee, noodles, or on its own.

Tofu can also be used to make a sweet and sticky orange dish. The tofu is coated in cornstarch and fried until crispy, and then a sauce made from orange juice, soy sauce, rice vinegar, and brown sugar is poured over the top.

So, as you can see, tofu is a versatile ingredient that can be used in a variety of sweet dishes. Whether you're looking for a savoury dish or a sweet treat, tofu is a great option to consider!
