This refreshing cocktail is the perfect balance of crisp mint, bright citrus, smooth tequila, and just the right kick of jalapeño to keep things interesting. Rim the glass with Tajín for an extra burst of zesty spice.
Rub the rim of a rocks glass with the lime wedge and dip half of the rim into Tajín.
Add the jalapeño slices, mint leaves, lime juice, and simple syrup to the glass. Using a muddler or the back of a wooden spoon, gently press the ingredients together just until the mint becomes fragrant and the jalapeño releases a bit of its heat. Be careful not to over-muddle the mint, as it can become bitter.
Fill the glass to the top with crushed ice. Pour in the tequila and stir gently until well chilled. Top with the club soda and give the cocktail one final, gentle stir to combine.
Nestle the mint sprig into the ice, garnish with the lime wheel and Fresno chile and jalapeño ring, and serve immediately.
