Sorry but they had someone out sick a few days so they were down a person, I didn't have the heart to ask him. I did try it when I got back home. I reduced white wine with a little fresh garlic, added both tequila and triple sec, reduced that and added Louisiana hot sauce. Once it reduced for a bit I put in the uncooked shrimp with a little flour to thicken. Finished with some butter to add richness. It had a very similar taste but the color was a little off and was hotter than Andy's. I have to keep experimenting with amounts but I'm close.

It will never match Andy's recipe but I need my margarita shrimp fix satisfied more than twice a year so I'll keep trying.
