Go ahead, lick your fingers. These chicken wings, fully flavored with sesame and ginger, are good cold, too–great in a picnic basket. The marinade makes a delicious dipping or stir-fry sauce, as well—bring to a boil and whisk in a teaspoon of cornstarch.
Arrange chicken wings in a single layer in a 9x13-inch baking pan.
In a medium-size saucepan over medium-high heat, bring stock to a simmer; then stir in remaining ingredients. Let cool to room temperature. Then pour over chicken, cover tightly with plastic wrap, and refrigerate 36-48 hours. Stir every 4 hours.
Put oven rack in middle position and heat oven to 375º.
Remove wings from marinade, shake off excess, and spread in a single layer on a rimmed baking sheet. Bake 45 minutes, turning once halfway through, until deep golden-brown. Transfer to a cooling rack and serve hot or at room temperature.
