Meanwhile, when chicken has been baking 35 minutes, begin glaze. Combine water, balsamic vinegar,
soy sauce, and sugar in a large skillet (NOT SAUCEPAN or it will take much longer to reduce) and simmer for 10-15 minutes or until reduced to a sticky glaze. The sauce thickens rapidly at the very end, so watch closely so it does not burn. Stir in
Sriracha to taste.
