1 pound boneless skinless chicken thighs, cut into 1-inch chunks
1 bunch green onions, cut into 1-inch pieces
1/2 cup soy sauce
1/4 cup mirin
1/4 cup sake
1/4 cup water
1/4 cup brown sugar
Vegetable oil for brushing
Directions
In a saucepan, add soy sauce, mirin, sake, water, and brown sugar. Cook on medium heat for 30 minutes or until slightly thickened. Remove from heat and allow to cool.
Soak wooden skewers in water for 20 minutes and then drain.
Alternate pieces of chicken and green onions up the length of each skewer, ensuring to leave space at the bottom for a handle.
Brush both sides of the chicken skewers with vegetable oil and place on a hot grill/under the broiler on an oiled wire rack. Cook for three to four minutes on each side.
Brush on soy glaze, cooking again for two to three more minutes on each side until deeply caramelized and cooked through to the middle.
