I chose this recipe from a number of chicken tikka masala recipies available on the web because the ingredients sounded the most chicken-tikka-masala-like. The results were oh so close, but I feel like there's something the Indian restaurateurs are keeping from us home chef types - something was definitely missing, and I have no idea what it was.
We went out for Indian food this past weekend (to India Palace in Somerville!), where I examined my chicken tikka masala in ways that must have appeared mysterious to our server. Their sauce was thicker, and tangier, and more orange in color. Not helpful!
