Pickled onions such as these are most often used as a garnish for tacos, burritos, and guacamole in Mexican cuisine. I think they are just as delicious on most of the burgers in this book, and they add a level of intrigue that raw onion slices could never do. The fresh lime juice is essential for its fresh, clean flavor as well as its acidity. If you want to pump up the volume on flavor and add a bit of heat, try adding a few whole jalapeño or serrano chiles to the mix.
