Carol - others have said they had Andy's recipe but have not shared it. I'm hoping that the OP will share. In the event that they don't this may be an alternative. I'm not comparing as Andy's margarita shrimp were one of a kind as he was.

I made Bang Bang shrimp for Superbowl and they were very good. You can make them as spicy as you like. I also did not use frozen popcorn shrimp but rather fried my own medium sized.
