Set instant pot on Saute mode set at NORMAL heat. Add butter & olive oil. When they begin to become hot gently release the chicken drumsticks and sear them until golden on all sides. Once done, set them aside on a plate with the help of a pair of tongs. You'll have lots of brown bits stuck at the bottom of the pot due to the ssearing process. Don't worry, we'll be deglazing the pot in the next step and the brown bits will help boost the flavor of the dish.
