In a large bowl with chicken add yogurt, lemon juice. Stir in 1/2 of garam masala spice (see above ingredients). Cover and refrigerate for 1 hour.

Add oil to preheated pan. Cut chilli in small pieces and saute for a minute. Turn down to medium heat. Now add crushed garlic and ginger fry for 2 minutes till they turn slightly brown.

Add the onion and sauté, stirring occasionally, until light brown and caramelized, about 5 minutes. Now add the rest of garam masala spice(see above) and mix well for 2-5 minutes.

Add tomatoes and stir. Turn heat very low, stir occasionally, cook till tomatoes get mushy. Lastly add the teaspoon of tomato paste. (Patience here, can take up to 20-25 minutes of your time!)

Now turn up heat and add marinated chicken, stir well. Cook from all sides for 5-8 minutes. Simmer on low heat until sauce thickens, about 20 minutes.

The chicken should be cooked now and sauce will have thickened. Lastly add cream and stir well! Transfer to a serving platter, and garnish with fresh cilantro.
