Ingredients: Japanese horseradish (Kona wasabi) 70.3%, MUSTARD flour 28.6%, turmeric, antioxidant: E300, colorant: E133, acidulant: E330.

Allergens: contains MUSTARD.

QUID: Kona Wasabi Japanese horseradish 70.3% is declared because it is highlighted in the name.

Aroma & Flavor

Clean, green, volatile heat from isothiocyanates; sharp “nasal” lift with a quick fade and minimal afterburn.

Culinary Uses & Pairings

Serve with sushi and sashimi, soba, tempura dips, steak tartare, creamy sauces (mayonnaise, crème fraîche), avocado spreads, and cucumber salads. Great with tuna, salmon, beef, nori, and rice.

Mixing Powder to Paste

Whisk 1 part powder with 1 part cold water to a firm paste. Cover and rest 3–5 minutes for heat development, then serve immediately. Avoid heating; add at the table.

Dosage & Tips

• Guideline: 0.5–1 tsp paste per 250 g (9 oz) fish or rice.
• For sauces: 1 tsp paste per 200 g (7 oz) base; adjust to taste.
• Color varies by blend; intensity fades after mixing—prepare just before serving.

Storage & Shelf Life

Keep tightly closed, cool, dry, and light-protected. Use soon after opening for peak pungency.

FAQ

Is this the same as fresh wasabi?
No. This is a seasoning blend; fresh wasabi is the grated rhizome of Eutrema japonicum.

Why is the allergen shown as MUSTARD?
EN rule: only the allergen word appears in ALL CAPS in the text; MUSTARD is present in the blend.

How can I keep the heat strong?
Mix right before serving, rest covered for 3–5 minutes, don’t heat, and serve promptly.

Can I replace fresh wasabi with this powder?
Yes, for everyday use; expect a similar style of pungency, not the exact fresh rhizome nuance.
