Salt-rimmed margaritas (or salt-rimmed anything, really) may be currently out of favor, but here’s one idea if you want to bring the trend back at your home bar: Use colored salts instead of boring old white ones.
The Spice Lab, which markets over 180 types of sea salt alone, has recently launched three sea salts designed specifically for margies. Available in blue, yellow, orange, or magenta, these brightly colored salts have no added flavor (hence no review, it’s just straight salt), but are artificially and naturally colored to put some pigment on the rim. (Warn guests in advance that it isn’t sugar!)
$3 gets you a 4 oz. bag (which is plenty of salt for even a large party of margarita guzzling).
