I've never been a huge fan of Mudslides. I acknowledge this is an unpopular opinion, it's just...you know, if I want ice cream, I want ice cream. If I want a cocktail, I don't want to add hundreds of calories to it; I'd rather have the cocktail...and then, maybe later on, have ice cream that doesn't taste like alcohol. You know?
But apparently real Mudslides - by which I mean the ones made where the drink was invented, The Wreck on Grand Cayman's Rum Point - don't have any ice cream in them at all. As the story goes, they were created in the 1970s when a customer came in wanting a White Russian (vodka, Kahlua, and cream), but since the bar was out of cream, the bartender substituted Bailey's Irish Cream. He threw it all in a blender, and ta da: A drink that's milkshake-level delicious, but not saturated in sweetness. (So you can have two. Just proceed with caution; these may not taste like anything but wonderfulness, but they're deceptively strong.)
