Tuna Tataki with Ponzu Sauce

Tuna Tataki with Ponzu Sauce

You’ve probably had tuna tataki as an appetizer at whatever sushi restaurant you dine at. You end up paying $10 for a couple of slices of tuna. You can easily make twice the amount of tuna tataki at home for a fraction of the price and still have it be restaurant quality.

The most important thing in making tuna tataki is to have the highest sushi grade possible. You can find it fresh at most higher end grocery stores and fish markets. I found a nice piece of sashimi grade yellowfin cut into a rectangular block that was vacuum sealed and frozen at my local Asian for about $13lb. It was better quality than what I expected. With a block that size, I was able to cut 4 equal rectangular bricks out of the loin. The tuna gets seasoned on the 4 long sides with sea salt and cracked pepper. Make sure to let the tuna rest at room temp for 30 minutes before cooking.

When ready to cook, heat up some cooking oil in a sauté pan over high heat. Place one of the loins in the pan, searing for no more than 20 seconds. Then cook the other 3 sides for 20 seconds each. I literally count to 20 out loud because the cooking process goes by quick. The goal is to have an 1/8” sear around the entire block. Then let the loin cool completely before slicing. Slice the loin into 1/4” slices. I arranged the tataki on a plate and spooned over some homemade ponzu sauce, which is a Japanese citrus soy sauce. Garnish with sesame seeds and you’ll have one of the best and easiest to prepare appetizers that will impress many a dinner guest.

Ingredients

8 oz sashimi grade yellowfin tuna
sea salt
cracked black pepper
2 tbsp vegetable oil

Ponzu Sauce

1/4 cup soy sauce
1/4 cup lemon or lime juice freshly squeezed
2 tbsp mirin
0.2 oz bonito flakes 1 packet
2”x3” kombu

Garnish

sesame seeds

Instructions

Mix all of the ponzu ingredients together. Let sit in the refrigerator for 24 hours.
Strain the ponzu sauce. Set aside.
Let tuna sit at room temp for 30 minutes before preparing.
Cut the tuna loin in half, then cut 2 equally sized blocks out of the loin. The piece of tuna I had was 1lb, and I only needed half of it. I vacuum sealed what I wasn’t going to use and froze down.
Season the tuna with sea salt and cracked pepper on the 4 long sides, leaving the two short square sides unseasoned.
Heat up vegetable oil in a small nonstick skillet over high heat; almost to the point where the oil begins to smoke. Place one of the tuna blocks in the center of the skillet, searing for no more than 20 seconds.
Flip over to the next side and sear for 20 seconds.
Flip to the next side and sear for 20 seconds. Flip onto the 4th side and sear for a final 20 seconds.
Let the tuna rest for a minute or two. You don’t want to cut the tuna when it is still hot.
Slice the tuna no more than a 1/4” thick.
