Traditional shrimp scampi recipes call for using white wine and when I make a larger batch of shrimp scampi, I add it. Shrimp scampi does not need to be made with wine. Since this is a single-serving dish, I don't think it's necessary to add it at all. You'd only be using a splash, maybe a tablespoon or so. That's why I left wine off of the ingredient list. My suggestion is to add wine only if you want to - and if you do, just add a very small amount. If you've opened a bottle and are enjoying a glass, then by all means add a little. If you don't have wine, then go ahead and make this shrimp scampi without wine - you won't miss it.
