Tips for a Perfect Rim for your Margarita

A classic margarita needs that signature salty finish, but you don’t want clumps of salt falling into the drink itself. The trick to a perfect rim is simple and keeps the salt exactly where it belongs: on the outside of the glass.

Use a lime wedge, not water: Cut a small slit in a fresh lime wedge and run it around the rim of your empty glass. The sticky lime juice holds the salt much better than water and adds an extra hit of fresh citrus right where you take a sip.

Roll, don’t dip: Instead of dunking the glass straight down into a plate of salt, pour your coarse salt onto a small plate and tilt the glass on its side. Gently roll just the outside edge through the salt. This coats the outside perfectly while keeping the inside clean.

Skip the store-bought mixes and enjoy a real, refreshing classic. Grab your favorite glasses, salt those rims, and enjoy!
