Spicy Margarita

If you'd like a salt rim, pour 1 tablespoon kosher salt onto a small dish. Moisten the rim of an old-fashioned glass with a lime wedge. Invert the glass into the salt, turning it as needed, to coat the rim.

Fill the glass with ice. Juice 1 medium lime until you have 3/4 ounce. Cut 4 (1/4-inch) thick rounds from 1/2 medium jalapeño.

Place the lime juice, 2 of the jalapeño rounds, 2 ounces blanco tequila, and 1 ounce triple sec in a cocktail shaker. Fill the shaker with ice, seal, and shake until the outside of the shaker is very frosty, about 20 seconds.

Pour through a fine-mesh strainer into the glass. Garnish with the remaining 2 jalapeño rounds.
