What is Nigari Tofu: Comprehensive Guide to Its Benefits and Uses

What Is Nigari Tofu

Nigari tofu is a type of tofu made by coagulating soymilk with nigari, a natural coagulant derived from seawater. Nigari contains mostly magnesium chloride, which gives the tofu a distinct taste and texture. This tofu is popular in Japan and other Asian countries for its rich nutritional profile and versatile culinary uses.

Origins and History

The origins of nigari tofu trace back to ancient Japan, where it has been a staple part of the local diet for centuries. Nigari, the coagulant used to create this tofu, is obtained by evaporating seawater and collecting the remaining solid minerals. This process has been practiced in Japan for over a thousand years, and the resulting tofu quickly became a favorite for its subtle flavor and smooth texture.

Nigari Vs Calcium Sulfate Coagulants

There are two primary coagulants used for making tofu: nigari and calcium sulfate (also known as gypsum). Nigari (magnesium chloride) results in a softer, smoother texture, while calcium sulfate creates a firmer tofu with a more crumbly texture.

Here’s a comparison of the two coagulants:

Nigari (Magnesium Chloride):

• Soft and smooth texture
• Subtle flavor
• Slightly higher in fat and potassium
• Slightly lower in protein, fiber, and calcium
• Popular choice in Japan

Calcium Sulfate (Gypsum):

• Firm and crumbly texture
• Neutral flavor
• Slightly higher in protein, fiber, and calcium
• Slightly lower in fat and potassium
• Common choice in Chinese cuisine

Despite their differences, both coagulants provide essential nutrients and can be used to create a variety of tofu dishes. The choice between nigari and calcium sulfate depends on the desired texture and flavor of the finished tofu.

In conclusion, nigari tofu is a delicious and nutritious food with a long history in Japanese cuisine. Its unique texture and subtle flavor make it a versatile ingredient for a wide range of dishes. With the added benefits of magnesium chloride from nigari, this tofu stands out as a healthy and delicious option for those seeking a plant-based protein source.

Making Nigari Tofu

Ingredients and Preparation

To make Nigari tofu, gather the following key ingredients: soybeans, water, and nigari. Nigari is a coagulant made of magnesium chloride, derived from seawater or brines¹. Begin by preparing soy milk with soybeans and water. This milk serves as the base for the tofu, similar to how dairy milk is for cheese.

Process and Techniques

To make Nigari tofu, start by heating fresh soy milk in a heavy bottom pot on medium-high until just scalding, around 76°C/170°F². Stir the scalding soy milk in a figure-eight motion and add the nigari. Continue stirring for 30 seconds before removing the mixture from heat.
