To a cocktail shaker add ice and all ingredients except the garnish.
Shake until the outside of the shaker becomes very cold in your hand.
Strain into a coup or over ice in a rocks glass.
Garnish with a cherry (or two) and a orange wedge.
Notes
If you prefer, make your own homemade sour mix and substitute for the lemon juice and simple syrup. For the modern version it's best to dry shake the ingredients (without ice) for 10-15 seconds before adding ice and then shaking in a cocktail shaker until cold. This helps incorporate the egg white better and create that foamy top.Egg whites are roughly 1 ounce each, so you only need half an egg white to make a single serving of the modern version of Amaretto sour. This makes it a great cocktail to shake up two at a time—great for a party!
