No, that’s not a typo. Depending on whom you talk to, this cheese-stuffed burger is either called a “Juicy Lucy,” or a “Jucy Lucy.” That’s because two restaurants in Minneapolis claim to have invented it, and they spell it differently. The 5-8 Club goes with “Juicy,” while Matt’s Bar saves a character and spells it, “Jucy.” Unless you end up on some kind of cheeseburger related trivia show, this is probably useless information, but hey, you never know.
The cheese stuffing really does keep the meat juicier, and the mouthfeel is noticeably different that what you experience with a burger that has cheese melted over the top. However, for this to work you need to keep the cheese inside, which means making sure you thoroughly and thoughtfully press the edges of the two patties together.
