Use fresh Key lime juice to give this margarita a tropical flair. Instead of simple syrup to balance the tart lime flavor, use agave nectar, a sweetener produced in Mexico that's sweeter than sugar.
Rub rim of a rocks or margarita glass with lime wedge, then dip in coarse salt.
Combine Key lime juice and remaining ingredients in an ice-filled shaker. Shake vigorously, and pour into prepared glass.
For a spicy jalapeño version, add 1 1/2 teaspoons jalapeño chile sauce to the shaker.
