Game plan: A fizz, or Delmonico glass is a highball-style glass but just a little shorter, with an 8- to 10-ounce capacity. Since the fizz-type drinks containing egg are served without ice, this glass is preferable to the standard highball.
A Royal Fizz is a Golden Fizz with the whole egg, not just the yolk.
