Wasabi

What is Wasabi?

Wasabi, sometimes referred to as Japanese horseradish, is a spicy and pungent green condiment that is used to flavor many traditional Japanese dishes. It is made from grated wasabi root and typically served with sushi and sashimi. Wasabi is a key ingredient in many Japanese cuisines, and its unique flavor has made it popular around the world.

The Origin of Wasabi

Wasabi is native to Japan, and its first use as a condiment was recorded in the 8th century. Its precise origin is unknown, but it is believed to have been cultivated near hot springs in Japan. This explains why it prefers larger amounts of water and moist conditions, as those are necessary for its growth. Traditionally, wasabi was ground fresh from a Daikon radish and served in its wet form.

The Production Process of Wasabi

The preparation of wasabi requires a precise combination of natural elements, temperatures, and careful monitoring. Additionally, it is a slow process, and the root can take up to 18 months to develop its distinctive flavor and aroma.

The growth process begins by selecting the Daikon radish root and then cutting it in half. The root is then wrapped in natural casing, such as straw, and placed in cold, running water from a nearby springs. Doing so allows oxygen and nutrient-rich water to reach the root. This is necessary for its growth. The root is placed in tanks that are continuously flushed with water, and the temperature and oxygen levels are carefully monitored. After one or two months, the root will begin to sprout and the color of the root will turn from white to green.

Once the root has been grown and aged to the appropriate stage, it is peeled and grated. This is done with a specialized tool, similar to a cheese grater. The powdered wasabi is then combined with water and other ingredients, such as mustard and horseradish, to create a paste. At this point, the paste can be used fresh or packed and shipped for commercial sale.

The Journey of Wasabi to the Dinner Plate

Once it has been prepared, wasabi must travel from its source to the dinner plate. But how does wasabi get from the farm to the diner?

The first stop for wasabi is the processing plant. At the plant, the freshly picked wasabi roots are washed and cut in half. Then, the root is placed in a tank where it can soak for several weeks or months, depending on the environment and desired flavor. Once the wasabi is ready, it is peeled and grated on a production line. The grated wasabi is then blended with other ingredients to create the traditional paste that is commonly used.

After the wasabi paste is ready, the next step is shipping and distribution. Depending on the size and type of restaurant, the wasabi may be shipped directly to the restaurant, or it may be sent to a storage facility before being distributed. If it is sent to a storage facility, it must be kept cold and refrigerated to maintain its quality. Additionally, the wasabi must be transported in an airtight container to prevent spoilage during the journey.

Once the wasabi has been shipped to the restaurant, a chef or a sushi chef is responsible for preparing it and serving it to customers. Typically, a sushi chef will place a spoonful of prepared wasabi onto a small plate and then mix it with soy sauce before serving it to customers. This combination is known as “wasabi-soy sauce”, and it is served alongside sushi and sashimi.

Conclusion

Wasabi is a popular condiment with a unique flavor that is beloved around the world. From its growth near hot springs in Japan, to its preparation and distribution, wasabi has taken an interesting journey to get to the diner’s plate. While there is a lot of work that goes into preparing and transporting wasabi, the end result is worth the effort, as it adds a tasty and flavorful kick to many traditional Japanese dishes.
