The Northern Royal Fizz

Preparation:

Into a chilled, empty collins glass pour soda water 1/4 of the way up. Combine other ingredients into mixing tin, shake without ice for 30 seconds, then shake with ice for 15.

Slowly strain into the collins glass. It will fizz up, stop pouring when it almost reaches the top.

Wait 2 minutes, now slowly pour the rest of it through the middle of the foam. The foam should slowly rise up over the glass.

No Garnish. No Straw.

Using a whole egg in a fizz makes it ‘royal fizz’
Egg white only would be a ‘silver fizz’
Egg yolk only would be a ‘golden fizz’
