Fill the highball glass with 4 to 6 ice cubes, packing them firmly to keep the drink chilled.

Rub a lime wedge around the rim of the glass, then dip the rim into a small shallow dish of tajín seasoning to coat evenly.

Squeeze 0.5 ounce of fresh lime juice directly into the glass over the ice.

Pour 0.25 ounce of hot sauce into the glass, starting with less and adjusting to taste.

Stir the lime juice and hot sauce together with a bar spoon for about 10 seconds to combine.

Tilt the glass at a 45° angle and slowly pour 12 ounces of Mexican lager beer over the back of a bar spoon to minimize foaming.

Give the mixture a gentle stir for 3 to 5 seconds to marry the flavors without losing carbonation.

Drop a lime wedge into the glass as a garnish and serve immediately while the beer is cold and the carbonation is lively.
