1. You can cook the chicken normally without using pressure cooker in a normal saucepan. Definitely it tastes better than the pressure cooked version!!!
2. Do not add more water than above, even if you add less it is fine. Chicken tends to release its water and if you add more, then you may have a watery curry as the final result.
3. I love adding potatoes to this curry, as it give a lovely flavor... but since I don't have a potato-friendly family, I avoid it.
4. You can even substitute water with coconut milk - that makes it tastes just too good!
