Flounder Fin – Engawa Grade B (エンガワ B級) – Japanese Flounder Fin 1kg for Malaysian HORECA

This Grade B (B級) engawa at 1kg provides excellent sashimi and sushi-grade flounder fin at a more accessible price point versus premium Grade AA engawa. Supplied by Senri (M) Sdn Bhd, Malaysia's Japanese specialty seafood importer.

4. What cuisine type is it associated with?

Japanese cuisine — sushi nigiri (engawa nigiri/縁側握り), sashimi platter component, and omakase specialty cut. Engawa is a coveted sushi bar item ordered by Japanese cuisine enthusiasts specifically.

5. What is the commercial value of this product?

Engawa is one of the most prized and highest-priced cuts in Japanese sushi culture. Grade B offers the authentic engawa experience at a lower food cost than AA grade, improving margin on engawa menu items while maintaining authenticity.

6. How is it used in a commercial kitchen?

Thaw overnight at 0–4°C. Slice thinly across the grain for sashimi portions (approximately 15–20g per slice). For nigiri: press a thin slice onto hand-formed sushi rice. The fatty, gelatinous texture pairs beautifully with a touch of ponzu and fresh wasabi. Can also be scored and lightly torched (aburi/炙り style) for a warm, slightly caramelised preparation.

7. What is the recommended serving size?

Approximately 30–50g per person as a sashimi portion (2–3 slices). For nigiri, 15–20g per piece. A 1kg pack provides approximately 20–33 individual sashimi portions or 50–65 nigiri pieces.

8. What is the yield?

After trimming any cartilage or connective tissue, yield is approximately 85–90% of raw weight — approximately 850–900g of usable engawa per 1kg pack.

9. What is the revenue potential?

Engawa nigiri is priced at RM 8–18 per piece in Japanese restaurants. A 1kg pack at 50 pieces can generate RM 400–900 in nigiri revenue. Sashimi portions at RM 28–50 per serving (3 slices) can generate RM 560–1,000 per kilogram.

10. What is a margin example?

If 1kg costs approximately RM 60–90, and generates RM 500 in nigiri revenue (50 pieces at RM 10 each), gross profit is approximately RM 410–440, giving a food cost of approximately 14–20%. Exceptional for a premium sushi ingredient.

11. How should it be commercially positioned?

Position as value-grade engawa delivering the authentic fatty, chewy flounder fin experience at a more accessible food cost than premium AA engawa. Feature prominently on sushi menus — customers who know engawa will seek it out.

12. What are the outlet benefits?

Lower food cost versus AA engawa with comparable eating quality. Large 1kg format supports high-volume sushi service. Authentic Japanese sushi ingredient that drives menu differentiation.

13. How does it contribute to menu profitability?

Grade B pricing with premium menu pricing delivers food costs as low as 14–20% for a specialty sushi item that commands high menu prices. Strong margin contributor to sushi bar profitability.

14. What are the storage conditions?

Store frozen at -18°C or below. Do not refreeze once thawed. Maintain cold chain throughout.

15. What is the shelf life?

Typically 12–18 months frozen. Check packaging for best-before date.

16. What happens after thawing?

Use within 24 hours. Keep refrigerated at 0–2°C. Cover to prevent colour oxidation. Use promptly for optimal texture and flavour.

17. What are the handling risks?

Maintain sashimi-grade cold chain standards. Thaw under refrigeration only. Allergen: fish. Slice with a sharp, clean Japanese knife for best texture results.

Sold per 1kg pack. MOQ and volume pricing from Senri (M) Sdn Bhd. Contact supplier for bulk order pricing.

22. How frequently should it be reordered?

Weekly for active sushi operations. Stock 1–2 weeks supply based on expected weekly nigiri and sashimi volume.

23. Is it suitable for central kitchen operations?

Yes. Portion at the central kitchen level and distribute chilled to outlet sushi counters for daily use.

24. How does it compare to alternatives?

Engawa Grade B offers better cost efficiency than Flounder Fin Engawa AA (500g from the Senri range) while delivering comparable flavour. The 1kg bulk format provides better value for high-volume operations. The Grade B classification does not affect the core engawa eating experience that sushi enthusiasts seek.

25. When should an outlet choose this product?

Choose when engawa is a regular sushi bar menu item and volume purchasing at a more competitive price point is desired. Ideal for sushi bars serving 50+ engawa nigiri per day where Grade AA would be cost-prohibitive.

26. What are the alternatives if unavailable?

Flounder Fin Engawa AA 500g (premium grade from the Senri range) as the premium alternative. For a different but similarly rich fatty sushi experience, yellowtail belly (Buri Toro) or swordfish belly (Mekajiki Toro) can substitute on premium sashimi plates.
