In a small bowl, mix cornstarch and water. Add all sauce ingredients to a small saucepan including cornstarch mixture. Bring sauce to a low simmer and cook for about 3-5 minutes. When sauce lightly thickens, remove from heat and transfer to a bowl to cool.
While your sauce is cooling, preheat oven to 400 degrees.
Line a baking sheet with a lightly oiled sheet of foil. Place salmon filets on the sheet and baste generously with sauce, reserving about half of the sauce for later use.
Place salmon in the oven and bake for 14 minutes. When salmon is nice and flakey, it's ready.
Remove salmon from the oven and baste with sauce again. Place salmon under the broiler for about a minute or until you get a golden lightly charred top.
Serve salmon over a bed of steamed rice with a sprinkle of red pepper flakes, chopped green onion and sesame seeds. Enjoy!
Notes
*Store leftover salmon in an airtight container in the fridge for up to 2 days.* If you don't have fresh garlic substitute for 1 teaspoon garlic powder* If you don't have fresh ginger substitute for ½ teaspoon ground ginger.
