Instant Pot Sesame Chicken (Six Sisters)

3 T. cornstarch (divided)
salt and pepper to taste
1 1/2 lb. chicken breasts, cut in pieces
2 T. sesame oil (divided)
6 T. low-sodium soy sauce
2 1/2 T. ketchup
pinch red pepper flakes
6 T. honey
3 T. water
1 T. sesame seeds

In a gallon bag, mix 2 T. cornstarch with salt and pepper. Add chicken and shake to coat. Add more cornstarch if needed. In Instant Pot, on saute function, heat 1 1/2 T. sesame oil. Add chicken and saute until all sides are brown. In a small bowl, mix soy sauce, ketchup, red pepper flakes, and honey. Pour over chicken pieces. Stir gently until coated. Place lid and seal. Cook on "manual" for 3 minutes, then do a quick release. ( I think I cooked mine for 6-7 minutes). Remove lid and add remaining sesame oil and honey and mix in. In another small bowl, mix water with remaining cornstarch. Pour in with chicken and gently stir. Push the "saute" button and let sauce thicken (2-3 minutes). Serve over rice and top with sesame seeds.
