Rub a lime wedge around the rim of a pint glass. In a shallow bowl stir together the Tajin and the kosher salt. Dip the glass in the salt mixture so it evenly coats the rim.
Add ice to a cocktail shaker and add tomato juice, mezcal, Worcestershire, hot sauce, and pepper.
Shake vigorously to combine. Strain into a collins glass filled with fresh ice.
Add the celery stalk to the glass. Thread the tomato, jalapeño and lime wedge onto a skewer. Serve immediately.
