For this one, you are going to need a wok. Heat the oil in the wok. Add the chicken and fry until it turns golden brown.
Now add the salt, the ginger-garlic paste and green chili paste. You need to cook this for 5 to 7 minutes on medium heat.
While the chicken cooks, take a medium-sized bowl and mix the yogurt, black pepper, cumin and coriander. After 5 or 7 minutes of cooking the chicken, add this yogurt mixture in it and cook for an additional 6 to 8 minutes.
When most of the water has evaporated and you can see the oil on the curry’s surface, add the heavy cream and butter. Cook for 1 to 2 minutes, then garnish with green chilies and the sliced ginger.
