What is Wasabi?

Wasabi is typically grown in Japan, and it is also known as Japanese horseradish. It has a searing feeling and a flavour that is incredibly potent and stimulating. Allyl isothiocyanate (AITC), often known as mustard oil and generated from cruciferous vegetables, is the source of the wasabi’s spiciness. When a wasabi glucosinolate combines with the enzyme myrosinase, AITC is created as soon as the root is extremely finely grated.

In Japan’s highland valleys, the plant grows organically along stream beds. Real wasabi is rare to get in restaurants since it is challenging to grow. Only a few regions in Japan are home to wild wasabi.

What is Wasabi?

Wasabi is a pungent and spicy condiment commonly used in Japanese cuisine. It is made from the grated rhizome of the Wasabia japonica plant, also known as Japanese horseradish. Wasabi is known for its distinctive and sharp flavor, similar to horseradish, but with a slightly different taste profile.

The Wasabia japonica plant is native to Japan and grows naturally in cool, mountainous regions with clean water. The rhizome, which is the part used to make it, is grated into a paste just before consumption to preserve its fresh and potent flavor.

Authentic wasabi is highly prized and considered a delicacy due to its limited availability and the difficulty of cultivating the plant. The majority of products available commercially are imitations made from a blend of horseradish, mustard, and green food coloring, as genuine wasabi can be quite expensive.

It is typically served as a condiment with sushi, sashimi, and other Japanese dishes. It adds a spicy kick and complements the flavors of seafood and rice-based dishes. The heat from it is often described as intense and short-lived, dissipating quickly after consumption.

In addition to its culinary use, it also has antimicrobial properties and is believed to offer some health benefits. It may help inhibit the growth of bacteria and improve digestion. However, scientific research on the specific health effects of it is limited.

It’s worth noting that wasabi should be consumed in moderation, as its intense flavor and spiciness can be overpowering for some individuals. Additionally, individuals with certain medical conditions or sensitivities may need to avoid or limit their consumption.

What Does Wasabi Taste Like?

Wasabi has a distinctive taste that is often described as pungent, sharp, and spicy. It is known for its intense heat and unique flavor profile. The flavor of wasabi is often compared to horseradish but with a slightly different character.

When you consume it, it initially provides a strong, tingling sensation in the nasal passages rather than a burning sensation on the tongue. This sensation is often described as a “wasabi kick” and is quite different from the spiciness of chili peppers or black pepper.

The taste of it is complex, combining elements of heat, sweetness, and earthiness. It has a refreshing and cooling effect on the palate. The flavor is often described as sharp, herbaceous, and slightly mustard-like. Genuine wasabi has a subtle sweetness that balances its spiciness.

The intensity of the flavor can vary depending on the freshness and quality of the wasabi. The potency of the flavor is typically strongest when the rhizome is freshly grated just before consumption.

While these imitations aim to mimic the taste of genuine wasabi, they may have a slightly different flavor profile. Overall, the taste of it is a unique combination of pungency, heat, sweetness, and earthiness. It adds a distinctive and memorable flavor experience to dishes, particularly when paired with sushi and another Japanese cuisine.

How to Grow Wasabi?

Growing it can be a challenging and specialized process, as it requires specific conditions and care. Here are some general guidelines for growing it:

Climate and Location

Wasabi plants thrive in cool, shaded, and humid environments. They require temperatures between 46°F (8°C) and 68°F (20°C) to grow well. Look for a location that provides shade, such as under the canopy of trees or in a greenhouse.

Soil Requirements

It prefers well-draining, fertile soil with a slightly acidic to neutral pH (around 6.0 to 7.0). The soil should be rich in organic matter and have good water retention capabilities. If your soil is not suitable, consider growing wasabi in raised beds or containers.


Wasabi plants require consistent moisture to thrive. The soil should be consistently moist but not waterlogged. Provide regular irrigation to keep the soil evenly moist, and consider misting the leaves to maintain humidity levels.


Wasabi can be propagated from seeds or rhizomes. If using seeds, soak them in water for 24 hours before planting. Rhizomes are the more common method and can be obtained from specialized nurseries or online suppliers. Choose healthy rhizomes with multiple buds or growing points.


Plant the rhizomes horizontally, with the growing points facing upward, at a depth of about 2 inches (5 cm) in the soil. Space the rhizomes around 12 to 18 inches (30 to 45 cm) apart to allow room for the plants to spread.

Shade and Protection

Wasabi plants prefer shade to protect them from direct sunlight. Provide shade using shade cloth, netting, or by growing them under taller plants or trees. This will help maintain the cool and humid conditions that the plants need.

Care and Maintenance

Regularly monitor the moisture levels in the soil and adjust watering accordingly. Mulching can help retain moisture and control weeds. Wasabi plants benefit from a balanced organic fertilizer applied according to the manufacturer’s instructions.


Wasabi plants take around 1.5 to 2 years to reach maturity. Harvest the leaves and rhizomes as needed, but leave some rhizomes in the ground to continue growing. Harvest the rhizomes by carefully digging them up with a garden fork or similar tool.

It’s important to note that growing wasabi can be challenging, and it requires specific conditions and expertise. It may be helpful to seek guidance from experienced growers or consult specialized resources for more detailed instructions tailored to your specific location and conditions.

How to Use Wasabi?
