Combine the coarse kosher salt and chili powder in a shallow dish. Take the half lime and cut a wedge from it, then run the lime wedge around the rim of a tall glass to moisten it. Press the moistened rim into the salt-chile mixture, rotating to coat the entire rim evenly.

Fill the prepared glass about two-thirds full with ice. Add the lime juice and mango nectar to the glass. If desired, add a few drops of hot sauce for extra kick and stir to combine. Top the drink with cold Mexican lager, pouring gently to preserve the fizzy head. Serve any remaining beer on the side so you can add more as you sip.

If you like an extra pop of color and flavor, garnish the cocktail with a few jalapeño slices. This adds a vibrant look and a subtle heat—I love using fresh jalapeños for that authentic touch. Enjoy your drink immediately while it's cold, adding more beer as desired.
