📜 How it began

⛵
Long ago

It’s said to come from meals fishermen ate on their boats[1]

🧂
The idea

With no way to keep fish fresh, it was a way to eat bonito that had lost freshness. Making tataki also reduces the fishy smell[1]

🍽
Today

In Kochi, it’s a standard in “sawachi” platters for celebrations and ceremonies[1]

💡 About the name

“Tataki” means “patting”. It’s said to come from patting salt or sauce into the fish so the flavor sinks in[1]

🐟 Best season

Autumn bonito is fatty and said to be best for tataki. Early-summer “first bonito” is popular too[1]

⚠️ Be careful

  • Only the outside is seared; the inside is raw. Use bonito labeled for sashimi (safe to eat raw)
  • Refrigerate it right away, and eat it the same day
  • Raw fish can carry anisakis (a parasite). Check carefully as you slice

Make it
