A couple of my favorite recipes, one Tikka Masala and one for butter chicken. I love McCormick's Garam Masala blend, I've tried 4-5 different brands over the years (Penzey's and the rest were Indian brands) and always go back to McComick's for the flavor profile.
For the butter chicken recipe, what really elevated to "this tastes like it's from a restaurant" was the ground fenugreek leaf powder. I had not seen that in recipes before and boy did it make a difference! I also bought Kashmiri chilli powder when I first made that recipe, also very nice.
