What the AI looks for in Bonito Flakes

Cut size
Large thin shavings (hanakatsuo) for dashi. Fine threads (itokezuri) or small packs for garnishing okonomiyaki, takoyaki or rice. Fine flakes over-extract or turn to mush in stock, while thick flakes look clumsy as a topping.
Arabushi vs karebushi
Karebushi is mold-cured for a cleaner, more refined flavor. Arabushi is smoked only and smokier. The curing style is what most separates premium katsuobushi from everyday flakes.
Pack format
Prefer nitrogen-flushed sealed bags or single-use packets. Shaved flakes oxidise and lose aroma quickly once opened.
Ingredients
The label should list only skipjack tuna (bonito). Some cheaper flakes are blends or contain additives.

Brands that matter

  • Yamaki: Large Japanese katsuobushi and dashi maker.
  • Marutomo: Another established Japanese bonito flake brand.
  • Kaneso: Japanese katsuobushi specialist.

What to avoid

  • Large open bags you will not finish within a few weeks of opening
  • Confusing instant dashi granules, which often contain MSG and salt, with plain flakes
