Pour whiskey, lemon juice, orange juice, simple syrup, and egg white (if using) into a shaker.
Dry shake (no ice) for about 10 seconds to create foam.
Add ice and shake again until chilled.
Strain into a rocks glass over a large ice cube or into a coupe glass straight up.
Add 2 dashes of bitters on top.
Garnish with an orange slice, blood orange wheel, or whole cloves.
Notes
Bourbon adds sweetness while rye gives spice. Infuse simple syrup with cloves for added depth. A large ice cube melts slower and chills longer. Garnish with clove-studded orange for extra aroma.
