Black Sesame Crusted Tuna Tataki

Black sesame crusted tuna tataki, heirloom tomato, kumquat pure

Let's prepare it!

Marination process Boil and flambe and let the alcohol evaporate.
Add the remaining ingredients to the first mixture and simmer to reduce around 25 to 35 Min. 
Dashi broth Boil the water with kombu and as soon as you move the pot away from the fire, add bonito flakes and let it rest for one night.
Add all the remaining ingredients to the dashi stock and cook to reduce for 20 min.
Strain and keep in mise en place.
Tuna marination Marinated for one night in a vacuum bag before cooking. 
Matsuhisa dressing method Rinse the shallot in cold water to get rid of the sharpness. 
Drain well.
Mix thoroughly shallots, soy sauce, vinegar, sugar, mustard powder, salt, and black pepper, in a bowl with four teaspoons of water.
When the sea salt has dissolved, add little by little the grapeseed and sesame oil, and blend well.
Kumquat gel method Strain the kumquat juice through a cheesecloth into a saucepan. 
In a separate saucepan combine the water, sugar and agar-agar. 
Set over medium-high heat, bring to simmer and whisk constantly for 5 min. (Warm the water without bringing it to boiling).
Once the agar-agar is completely hydrated into a simple syrup, slowly whisk it in the warm kumquat juice. 
Pour into a baking dish and refrigerate for 1 hour. Once set, cut it into small pieces and puree it in a blender until smooth. 
Pass through a fine-mesh tamis.
Finalize dish Heat a bit of oil in a non-stick pan over high heat. 
Place the tuna on a clean cutting board or plate, and season generously with sea salt and freshly grounded black pepper.
Sear the tuna for 15-20 seconds on each side, but be careful not to overcook.
Transfer the cooked tuna on a clean board and let it rest for about 5 minutes or cool it down with a blast chiller.
Roll and lightly press the tuna on the black sesame.
Slice it 3 cm high, and make sure to cut against the grain, then cut again by half and set it on the serving plate.
Garnish the tuna with blow-torched heirloom tomato, kumquat puree, seared kumquat and micro herbs. 
Serve with Matsuhisa dressing and sea salt flakes.
