Really, it's not shrimp scampi. It's all the elements of scampi but different. Scampi is lemon, garlic, butter, and parsley. This is similar but I used lime and cilantro. I exchanged scallops for shrimp. I always put a pinch of cayenne pepper in my scampi but since I was going in a different direction with the lime and cilantro, I traded the cayenne in and used a pinch of chipotle chili powder. It turned out great. Everyone at dinner that night raved about it.
