I dug this cocktail out of Gary Regan’s Bartender’s Bible while I was on the hunt for simple vodka cocktails. It’s sort of a banana version of an eggy Vodka Sour. While the recipe has you serving it on the rocks, I think in hindsight I would have made it without ice because it accentuates the egg foam on top better.

Take a crack at the Spymaster:

Spymaster

• in a shaker combine:
• 1 1/2 oz vodka
• 1/2 creme de banane
• 1/2 oz lemon juice
• egg white
• shake without ice (to foam up the egg), then add ice and shake again
• strain into an old fashioned glass
