Set the Instant Pot on SAUTE and keep it on NORMAL.
Add ghee, when the ghee becomes moderately hot add the whole garam masalas along with the bay leaf and allow them to siizzle for few seconds or until aromatic.
Next, add the flash marinated chicken and saute until the chicken begins to change color and becomes opaque from outside.
Lower the heat from NORMAL to LOW. Add the crispy onions, the dry spices (garam masala & star anise powder) and the whisked yogurt.
Give everything a very good mix and saute just for 1-2 mins.
Now, add 1 cup warm or hot water. This helps to build the pressure fast inside the Instant Pot.
Cover the lid of the Instant Pot. CANCEL the SAUTE. Seal the Valve and PRESSURE COOK on HIGH for just 1 min.
After 1 min when the Instant Pot begins to beep immediately do a quick pressure release by moving the valve from the SEALING to the VENTING position.
Now, strain the cooked Chicken to separate the stock. We'll need exactly 530 ml cooked chicken stock to cook the Chicken Pulao.
Measure the cooked stock and if you find it less than 530 ml add additional water to make it 530 ml in total.
