Mix soy sauce, hoisin sauce, sesame oil, brown sugar, garlic, ginger, and black food coloring(optional) in a small bowl and add to a zip lock bag. Add chicken wings and marinate for one hour or overnight.
Preheat oven to 400°. Line cookie sheet with parchment paper. Arrange chicken wings in a single layer, transfer marinade to a small saucepan. Bake chicken wings for 30 minutes. Flip over and bake an additional 30 minutes.
Bring marinade to a rolling boil and then simmer for 10 minutes. Mix water, cornstarch and add to the marinade. Simmer until sauce thickens, add sesame seeds and set aside.
Remove chicken wings from oven and place them in a large bowl, toss with the sticky marinade and serve.
Plating suggestion: Look up the scientific names of a variety of bats and print out labels. Arrange wings on a large cutting board above the labels and serve. Garnish with black sesame seeds.
