Kanzuri is a distinctive chile paste with a rich tradition, crafted exclusively in Myoko, located within Japan's Niigata Prefecture.

The Tojo family, who began commercializing this condiment in 1966, originally produced it solely for private consumption in small quantities.

Now, a bottle aged for six years, containing 2.5 ounces (70g), is valued at nearly $20.

What is Kanzuri Chili Paste?

Kanzuri chili paste is a distinctive condiment from Niigata Prefecture, Japan, known for its unique production process and robust flavor profile.

Made primarily from togarashi chilies, the paste undergoes a remarkable production cycle that begins with the chilies being left to ferment in the snow.

This method, known as 'yuki miso', naturally reduces the bitterness and saltiness of the chilies.

After the snow fermentation, the chilies are blended with salt and koji (rice malt) for further fermentation, lasting up to several years.

This lengthy process helps develop deep, complex flavors. Finally, yuzu (a Japanese citrus) and additional salt are added, introducing a bright, aromatic quality to the paste.

How Kanzuri is Made?

Kanzuri chili paste is crafted through a meticulous and traditional process that leverages the natural environment and local ingredients of Niigata, Japan.

The process involves several stages, each contributing to the unique flavor and texture of the final product.

1. Harvesting and Preparation

The process begins in the late summer when togarashi chilies are harvested at their ripest. These chilies are the primary ingredient in Kanzuri and are known for their vibrant red color and moderate heat.

2. Snow Fermentation

Once harvested, the chilies are washed and then placed outside in the cold winter snow. This stage typically occurs in December or January when the snow is plentiful.

The chilies are left to ferment in the snow for about three to four days. This unique method, known as 'yuki miso', leverages the natural cooling and insulating properties of snow to moderate the fermentation process.

The snow helps to leach out excess bitterness and salt, while subtly fermenting the chilies to enhance their flavors.

3. Mixing with Koji and Salt

After the snow fermentation, the chilies are removed from the snow and mixed with sea salt and koji, which is a type of rice malt used as a fermentation starter in many Japanese products like sake and soy sauce.

Koji introduces beneficial molds and bacteria that help in breaking down the chilies' complex sugars and proteins, thereby developing a rich umami flavor.

4. Lengthy Fermentation

Kanzuri chili paste is crafted using a meticulous process that begins with harvesting peppers, which are then mixed with salt and left to cure for six months.

In the coldest part of winter, typically February, these cured chilies are spread on the snow for three to four days in a process called 'yuki miso' or snow fermentation.

This method leverages the insulating properties of snow to naturally ferment the chilies, reducing bitterness and enhancing their flavors.

After their time in the snow, the chilies are blended with koji, a crucial rice mold used in many traditional Japanese fermentations like sake and miso.

Additionally, yuzu, a fragrant Japanese citron, is added, providing a bright citrus accent that pairs well with the chilies' heat.

The mixture is then placed in large barrels for a slow fermentation period ranging from three to six years.

During this time, the chilies, koji, and yuzu flavors integrate and evolve, resulting in a complex, nuanced, and aromatic flavor profile.

5. Addition of Yuzu and Final Adjustments

Towards the end of the fermentation period, yuzu zest and juice are added to the chili mixture.

Yuzu is a Japanese citrus fruit known for its fragrant and tart flavor, which adds a bright, aromatic lift to the paste.

Additional adjustments might be made, such as adding more salt or koji, to achieve the desired flavor balance.

6. Maturation

After all ingredients have been combined, the Kanzuri may undergo further maturation to allow the flavors to integrate fully.

This stage also helps in mellowing any harshness from the chilies and balancing the tartness from the yuzu.

Once matured, Kanzuri chili paste is packaged and prepared for distribution. It is typically stored in small jars or containers, maintaining its potency and flavor integrity for culinary use.

Why is It So Expensive?

Kanzuri chili paste commands a high price due to several factors that highlight its unique production and rarity:

1. Lengthy and Labor-Intensive Process

The traditional method used to create Kanzuri is extremely labor-intensive and time-consuming.

The process includes multiple steps such as the snow fermentation of the chilies, mixing with koji and salt, and a lengthy fermentation period that can last up to six years.

Each of these steps requires careful monitoring and manual labor, contributing to the overall cost.

2. Unique Fermentation Technique

The snow fermentation technique is a pivotal element in the production of Kanzuri chili paste.

During the coldest part of winter, typically in February, the salted chilies are placed on the snow for three to four days.

This unique method takes advantage of the natural snow environment, which cannot be hurried or duplicated in other settings, contributing to the paste's exclusivity and cost.

The impact of the snow on the chilies is multifaceted:

  • Bitterness Reduction: The snow helps leach out bitterness from the chilies, making them more palatable.
  • Sweetness Enhancement: Exposure to the snow also increases the natural sweetness of the chilies.
  • Fiber Breakdown: The cold conditions help break down the chilies' fiber content, resulting in a milder texture.

3. High-Quality Ingredients

Kanzuri is made from high-quality ingredients such as locally sourced togarashi chilies, sea salt, koji, and yuzu.

These ingredients themselves are premium, especially yuzu, which is a prized citrus in Japan known for its aromatic flavor.

4. Limited Production

The production of Kanzuri is confined to a specific geographical location and is produced in relatively small batches to maintain quality control.

This limited production capability does not meet the high demand effortlessly, thereby increasing its market value.

5. Aging Process

The aging process, which can extend up to six years, ties up the investment for a long time before the product can be sold.

This aging is crucial for developing the paste’s complex flavors and character but also adds to the overhead costs, including storage and maintenance.

Flavor Profile

Kanzuri chili paste features a sophisticated flavor profile with a moderate heat from red togarashi chilies, enhanced by the bright, tangy accents of yuzu citrus.

The addition of koji, a rice mold, brings a deep umami richness, while the unique snow fermentation process and extended aging contribute a subtle sweetness, making it milder and sweeter than similar condiments like Tabasco or Chinese doubanjiang.

In Niigata, where Kanzuri originates, it is commonly used to elevate the flavors of grilled dishes, hot pots, and even sashimi, showcasing its versatility and appeal in various culinary contexts.

Culinary Uses

Kanzuri chili paste is a versatile ingredient in Japanese cuisine, offering a distinctive blend of heat, citrus, and umami flavors that can enhance a wide range of dishes. Here are some culinary uses for Kanzuri chili paste:
