Jalapeño Margaritas

In a jar, steep the jalapeño and tequila; keep at room temperature for 3 days.

Strain the tequila into a large pitcher and discard the jalapeño. Stir in the orange liqueur, lime juice and sugar.

Pour the salt and a small amount of the margarita onto 2 rimmed plates. Dip the rims of 6 glasses into the margarita, then into the salt. Fill each glass with ice, pour in the margarita and serve.
