Add 30ml white rum, 30ml brandy, 30ml triple sec, and 30ml fresh lime juice into a cocktail shaker.
Fill the shaker with ice and shake vigorously for 10–12 seconds until well chilled.
Double-strain into a chilled cocktail glass.
Garnish with a lime wheel or twist and serve immediately.
The split base of white rum and brandy is the defining move here - rum lifts the drink with tropical brightness while brandy anchors it with warmth and body, a pairing that echoes the Sidecar's DNA while carving its own identity. Using fresh lime juice rather than lemon (as in the classic Sidecar) sharpens the citrus profile and ties the drink closer to its rum half.
