Step 1

Prepare grill for medium-high heat. Whisk brown sugar, vinegar, chili paste, fish sauce, Sriracha, and ginger in a large bowl. Add chicken and toss to coat. Remove chicken and thread 4 or 5 pieces onto each skewer.

Step 2

Transfer leftover marinade to a small saucepan. Bring to a boil, reduce heat, and simmer until reduced by half (about 1 cup), 7–10 minutes.

Step 3

Grill chicken, turning and basting often with reduced marinade, until cooked through, 8–10 minutes.
