In a shaker, add 3 parts bourbon whiskey, 2 parts lemon juice (fresh), 1 part simple syrup, and egg white.
Dry-shake for 30 seconds without ice.
Add ice and shake for another 20 seconds until chilled.
Strain into a chilled old fashioned glass filled with ice, then garnish with 1 Maraschino cherry, 1/2 slice orange, and a splash of Angostura bitters.
