Baked teriyaki chicken

1 tbsp cornstarch
1 tbsp cold water
1/2 cup white sugar
1/2 cup soy sauce..i used low sodium
1/4 cup apple cider vinegar
1 clove garlic minced
1/2 tsp ground ginger
1/4 tsp black pepper
12 boneless skinless chicken thighs..i used chicken breast.

In a small saucepan over low heat combine cornstarch, cold water, sugar, soy sauce, vinegar, garlic, ginger and pepper. Let singer stirring frequently until sauce thickens and bubbles.preheat oven to 425°.place chicken in a lightly greased baking dish.brush chicken with sauce.turn pieces over and brush again.bake in preheated oven for 30 minutes.turn pieces over and bake another 30 minutes until no longer pink and juices run clear.baste with sauce every 10 minutes during cooking. I thought it was good but needed a little extra flavor so next time I'm going to marinate my chicken for an hour in a marinade made with soy sauce , ginger, garlic powder and brown sugar..
