Season cornstarch with salt and pepper. Dip the shrimp in cold water and dredge in cornstarch, shaking off excess.
Place in a fryer, pre-heated to 350 degrees, and fry until fully cooked, approximately 4-6 minutes. Place into a mixing bowl lined with paper towels and season with salt and pepper.
While shrimp is cooking, place sauce in a saute pan on low heat and heat through. Place sesame seeds in a separate saute pan and toast until warm and set aside.
To assemble, arrange shrimp as desired on plate. Drizzle and even amount of sauce on all shrimp and top with sesame seeds and chopped green onions.
