for the chile-salt rim:
2 tsp. salt
1 tsp. chili powder

Combine the salt and chili powder and put on a small dish. Run a lime wedge around the rim of each glass then turn in the salt mixture.

for each glass:
1/4 c V8 (or other tomato based vegetable juice)
juice of 1/2 lime
dash of your favorite hot sauce (I like El Yucateco Chile Habanero)
dash worcestershire
Mexican beer, Modelo Especial or Tecate works well

After you rim each glass fill 3/4 of the way with ice. Add the ingredients in order, top with beer. Serve immediately.
Alternately, make the drink base in a pitcher, pour into glasses and top each with beer.
