Glorious Evening Fizz

Here's a somewhat random variation on the "Morning Glory Fizz", a curiously tasty cocktail that I stumbled across in Imbibe! and which has become a personal favorite hangover helper.  I made this one on a warm summer evening, hence the name, and it was just too tasty not to write down.

2 oz scotch

3/4 oz ginger syrup (a nice spicy version created by combining juiced ginger and sugar)

3/4 oz lime juice

3 dashes celery bitters

1 egg yolk

Rinse the inside of a fizz glass with absinthe and place in the freezer to chill.  Combine the above over ice, shake well, and strain into the prepared glass.  Top with 3-4 oz of chilled, carbonated cucumber water to taste, then twist a lemon peel over the top and discard.
