In a medium bowl, combine yogurt, lime juice, reserved 1 teaspoon each of garam masala, grated ginger, minced garlic. Then add cut chicken, toss until coated — cover and set in the fridge for a minimum of 20 minutes (or even overnight).
Next, heat instant pot on sauté mode then add the oil, and marinaded chicken (including any extra marinade), stir and let cook ~5 minutes.
Add remaining ingredients (except for coconut milk and cilantro), stir until combined. Cover with lid and set to pressure cook mode for 10 minutes, then manually release pressure.
Once cooked, stir in coconut milk, serve over rice, and garnish with cilantro.
Store and enjoy!
