Delicious! Butter chicken is one of my favorite Indian dishes and I love its creaminess and full flavor. I've made this recipe twice, with a few small tweaks, and have loved it both times. I use fresh ginger and 1 clove of garlic (grated) instead of the pre-made paste, though if you're in a bind you can also use ginger and garlic powder instead. The flavors won't be as deep, but it works. Also, instead of yogurt and half and half I have used 1 cup of heavy whipping cream, which adds enough thickness to the sauce that it doesn't need cornstarch. I haven't tried many versions of Butter Chicken, but this is a recipe I believe I will come back to over and over again.
