Pre-heat a fryer to 400 degrees F. Season the ahi on all sides with salt and pepper. In a food processor, add the edamames and shallots, pulse into small pieces. Add the eggs and pulse to mix.
Meanwhile, make tempura batter whisking the flour with soda water until a thick paste is formed. Fold the edamames with the tempura. Dip the ahi in the batter and fry for 3 to 4 minutes, until golden brown. Season lightly with salt and slice in half on the bias. The middle should be cool and rare.
To make the salad, in a small bowl, whisk together the wasabi, soy, vinegar, sesame oil, and 1/4 cup canola oil. Toss vinaigrette (save a little for garnish) with the sprouts, carrots, scallions, and season. Check for balance of flavor.
Using a 3 to 4 inch ring mold (2 to 3 inches tall), stuff with the salad and drizzle vinaigrette around. Place the ahi on top and de-mold. Garnish with sesame seeds.
