Preparation

• For a salted rim (optional), run the slit of the lime wheel around the rim of a chilled rocks glass (or a chilled martini glass if you prefer no ice) to moisten, then dip the rim into a small dish of kosher salt.
• Fill a cocktail shaker with ice and add the tequila, lime juice, agave nectar, and 3/4 fl. oz (1-1/2 Tbs.) water. Put the lid on the shaker and make sure it has a good seal.
• Shake vigorously until the outside of the shaker is frosty, 10 to 15 seconds. Strain into the prepared glass over fresh ice (if desired). Garnish with the lime wheel and serve.
