1½ ounces silver tequila
6 ounce fresh orange juice
½ ounce grenadine (or Chambord)
2 to 3 ounce chilled club soda (optional)
STIRRED OVER ICE: Pour the tequila and orange juice into an ice-filled highball glass, and stir. Float the grenadine or Chambord on top, and let it slowly descend through the drink. Top with club soda, if desired.
SHAKEN: Pour the grenadine or Chambord in the bottom of a chilled cocktail glass. Shake the tequila and orange juice with ice, and strain into the glass.
