I found a video by an Indian chef on Youtube. He really seems to know what he is doing. I absolutely love Indian food and I am always looking for good recipes. He also has a website that is worth looking at.
Butter chicken is a very popular dish in Indian restaurants in America. It also goes by the name Murgh Mahkni and Chicken Tikka Masala. I have posted on the subject here.
My recipe differs from the video just a little, I use tandoori chicken from the grill instead of chicken pieces sauteed in oil the way he does. I'm definitely going to try his recipe post haste.
