You just cannot go wrong with this drink: smooth and airy, with a gentle tang and a nice, foamy cap. Your dad likes it. Your bestie likes it. Even your co-worker who definitely does not like whiskey likes it. There's a reason a Whiskey Sour is known as the white T-shirt of cocktails.
A note on your shaking technique: cocktails like this one that call for egg white are usually shaken in two steps. The first is a so-called dry shake without ice — this emulsifies the egg white. Then, add ice and shake a second time, which chills and properly dilutes the drink. Cheers!

1/2 ounce fresh squeezed lemon juice
1/2 ounce fresh squeezed lime juice
1/2 ounce simple syrup
1 egg white

Combine ingredients in a shaker without ice, and shake vigorously to emulsify the egg white. Then, add ice to the shaker and shake again to chill. Strain into a rocks glass with ice, and garnish with a brandied cherry and a couple dashes of bitters.
