Salt the rim of margarita or rocks glass by placing a small amount of Sriracha on a plate, dashing the rim of the glass with Sriracha, then dipping the rim in salt.

Place ice in a cocktail shaker, then add in tequila, cointreau (or triple sec), lime juice, and Sriracha. Shake vigorously, then pour the margarita into the glass.

Garnish with a jalapeño wheel and enjoy.
