Key Lime Margaritas

Key limes, more aromatic than regular limes and known for their distinctive tart juice, add a punch of flavor to this cocktail. This recipe also calls for reposado tequila, which is aged in wooden barrels, where it develops a mellower flavor and amber color. A regular tequila would work fine as well.

Preparation time: 15 minutes

Ingredients

1 Key lime, quartered (optional)
Kosher salt for rims of glasses (optional)

Run a lime wedge (if using) around rim of each of 4 (6-to 8-ounce) glasses. Put salt (if using) on a small plate and dip glasses in salt to lightly coat rims.
