In a small bowl add ginger, garlic, green onion, cilantro, rice wine vinegar, sesame oil, soy, 1 tablespoon of canola oil, and sake. Whisk ingredients together.
Place 1 teaspoon of vinaigrette in each soup spoon.
Season scallops with salt and pepper.
Place sesame seeds on a plate. Pat down top and bottom side of each scallop in sesame seeds.
In a saute pan, over medium-high heat add remaining tablespoon oil. When oil is hot, add scallops, placing them sesame-crusted side down. Sear for approximately 1 minute, or until sesame seeds brown. Turn and sear on other sesame-crusted side for 1 more minute. Place 1 scallop in each soup spoon. Serve immediately.
* The same serving format can be achieved with only 4 spoons by replenishing each guests spoon for subsequent servings.
