Over the years tataki has become increasingly popular: beef, tuna, salmon, trout and even veal and deer tataki. But what is tataki actually? And what is tataki sauce?

Tataki originates from the Kōchi prefecture in Japan. The original dish is called katsuo-no-tataki. Katsuo (also known as Oceanic Bonito or Skipjack Tuna) is an important ingredient in the Japanese kitchen, for instance raw as sashimi and dried as katsuobushi (the flakes you need when making dashi).

The fish is seared very briefly in a huge rice straw fire. This way the fish becomes nicely coloured, the centre remains raw, and the flavour will be enhanced with smokiness. It is then sliced and served with a garlic, lemon (ponzu), soy and onion sauce, making Katsuo-no-tataki very different from other sashimi.

Unfortunately, most of us don’t have a straw fire at home, so you need a very hot pan to sear the fish. Bonito is not widely available where we live, but tuna is a great alternative. Beef is a good idea, salmon is a possibility, veal and trout are definitely not good alternatives.

What You Need

• Bonito (or Tuna or Beef Tenderloin)
• Light Soy Sauce (Tsuyu)
• Mirin
• Rice Vinegar
• Lemon
• ½ Garlic Clove
• Sesame Seeds
• Spring Onion
• Olive Oil

What You Do

We added lightly roasted sesame seeds to the dish. There are not included in the original katsuo-no-tataki so feel free to leave them out.
Combine light soy sauce, mirin and rice vinegar (ratio 3:1:1), add some lemon juice and the grated garlic. The garlic must be grated; it should nearly dissolve in the sauce. Quickly sear the bonito (tuna, beef) in a hot non-stick pan with just a touch of oil. When ready transfer to an ice bath. Wait for a minute or so. Remove from the water and use kitchen paper to dry the fish. Slice, serve on a plate, drizzle with the dressing, then add thinly sliced white spring onion, then sesame seeds (if using) and finish with some dressing.

PS

And the answers are: tataki is a method to sear katsuo (or in general fish or beef) in a straw fire (or over a grill or in a hot pan). Tataki Sauce doesn’t actually exist; it may refer to the sauce that is served with katsuo-no-tataki.
