Step 1

Add the amaretto, bourbon, lemon juice, syrup, egg white, and to a cocktail shaker without ice. Shake for 15 seconds (skip this first step if you’re not using the egg white).

Step 2

Add the ice to the cocktail shaker. Shake again for 30 seconds.

Step 3

Strain the drink into a glass; the foam will collect at the top. Garnish with a cocktail cherry.
