Combine equal parts of the kosher salt and Mexican seasoning powder mix on a flat plate. Rim the edge of the glass with a little bit of the lime juice, and then dip in the seasoning to coat the edge of the glass.
Combine the remaining lime juice, Worcestershire, liquid seasoning if using, hot sauce and black pepper in a tall glass. Stir and top off with the ice cold Mexican beer.
