The Blue Lagoon is one of those cocktails that just works. This French classic combines vodka, blue curaçao, and lemonade into something refreshing and surprisingly tasty. Sure, it’s bright blue and looks a bit wild, but that’s part of its charm. It’s been around since the 1970s and remains popular because it’s easy to make and even easier to drink. Perfect for summer afternoons or whenever you want something light and fruity without the complexity of more elaborate cocktails.
