Liquid tofu, also known as soft or silken tofu, is a type of tofu that has a high water content, giving it a soft, creamy, and custard-like texture. It is a versatile ingredient used in a variety of dishes, from savory sauces to sweet desserts. In this article, we will explore the process of making liquid tofu, its uses, and provide valuable tips and insights for those looking to incorporate this ingredient into their culinary repertoire.
Introduction to Tofu and Its Types
Tofu, also known as bean curd, is a food made from soybeans that have been ground into a paste, mixed with water, and coagulated using various agents such as calcium sulfate, magnesium chloride, or other salts. The resulting curds are then pressed into blocks of varying firmness, which can range from soft and silken to firm and extra-firm. Liquid tofu falls into the soft or silken category, characterized by its high moisture content and delicate texture.
Understanding the Coagulation Process
The coagulation process is crucial in making tofu, as it determines the final texture and consistency of the product. There are several coagulants that can be used, including:
- Calcium sulfate: This is a common coagulant used in traditional tofu production, which helps to create a soft and delicate curd.
- Magnesium chloride: This coagulant is often used in combination with calcium sulfate to create a smoother and more even texture.
- Gypsum: This is another type of coagulant that can be used to create a softer and more fragile curd.
Preparing the Soybean Paste
To make liquid tofu, high-quality soybeans are essential. The soybeans should be soaked overnight, then ground into a fine paste using a blender or food processor. The paste should be mixed with water to create a milky liquid, which is then coagulated using the chosen coagulant.
The Process of Making Liquid Tofu
Making liquid tofu involves several steps, from preparing the soybean paste to coagulating and straining the mixture. Here is a detailed overview of the process:
Step 1: Preparing the Soybean Paste
- Soak 1 cup of soybeans in water overnight.
- Drain and rinse the soybeans, then grind them into a fine paste using a blender or food processor.
- Mix the soybean paste with 2 cups of water to create a milky liquid.
Step 2: Coagulating the Mixture
- Add 1/2 teaspoon of calcium sulfate or other coagulant to the soybean mixture and stir well.
- Allow the mixture to sit for 10-15 minutes, until it has fully coagulated and separated into curds and whey.
Step 3: Straining the Curds
- Line a colander with cheesecloth or a clean, thin towel.
- Carefully pour the coagulated mixture into the lined colander.
- Allow the mixture to strain for 10-15 minutes, until most of the whey has been removed and the curds have reached the desired consistency.

What is liquid tofu and how is it different from traditional tofu?
Liquid tofu, also known as tofu paste or soft tofu, is a type of tofu that has a creamy, custard-like texture and a neutral flavor. It is made by blending extra-soft silken tofu with water or other liquid ingredients until smooth, resulting in a pourable, sauce-like consistency. This process breaks down the curds and releases the liquid, creating a uniform texture that can be used in a variety of applications. Unlike traditional firm or extra-firm tofu, which has a dense, sponge-like texture, liquid tofu is more versatile and can be used as a substitute for dairy products, eggs, or other thickening agents in recipes.
The main advantage of liquid tofu is its ability to easily absorb flavors and blend with other ingredients, making it an ideal base for sauces, marinades, and dips. Additionally, liquid tofu has a higher water content than traditional tofu, which makes it more prone to spoilage and requires proper storage and handling. Overall, liquid tofu offers a unique set of characteristics that can enhance the texture and flavor of various dishes, from savory stir-fries to sweet desserts. By understanding the differences between liquid tofu and traditional tofu, cooks can unlock new possibilities for innovative and delicious recipes.

Additionally, individuals can consider adding preservatives or acidity regulators, such as lemon juice or vinegar, to the liquid tofu to enhance its shelf life and stability.
Can I use liquid tofu as a substitute for dairy products in recipes?
Yes, liquid tofu can be used as a substitute for dairy products in many recipes, depending on the desired texture and flavor. Due to its high water content and neutral flavor, liquid tofu can be used to replace milk, cream, or yogurt in sauces, soups, and baked goods. Additionally, liquid tofu can be used to create vegan versions of dairy products, such as cheese sauces, creamy dips, and ice cream. When substituting dairy products with liquid tofu, individuals should be aware of the varying fat content and flavor profiles of each ingredient, and adjust the recipe accordingly.
When using liquid tofu as a substitute for dairy products, individuals can experiment with different ratios of tofu to liquid, as well as adding flavorings and thickeners to achieve the desired texture and taste. For example, adding lemon juice or vinegar can help to curdle the liquid tofu and create a cheese-like texture, while adding thickeners like cornstarch or tapioca flour can help to achieve a creamy consistency.
