Rim a rocks glass with a lime wedge to roll in Tajín or salt and fill with ice.

In a shaker, either muddle whole jalapeño slices or put in the chopped pieces without muddling.

Add lime juice, agave nectar, and Chicas Divertidas Blanco Tequila.

Fill the shaker with ice and shake well for 7-10 seconds.

Strain into the prepared rocks glass and garnish with a jalapeño slice and lime wheel.

For a touch sweeter margarita, use 0.75 oz of agave nectar.
