The Rum Sour is an exotic and warming twist on the famous Whiskey Sour. Here, amber rum replaces whiskey, delivering vanilla, woody, and slightly sweet notes, perfectly balanced by the acidity of lemon and the sweetness of sugar syrup. The whole drink can be enhanced with egg white, which brings a smooth, velvety texture. Perfect for fans of refined and balanced cocktails.

• 5 cl amber rum
• 2.5 cl fresh lemon juice
• 2 cl sugar syrup
• 1 egg white (optional)
• Garnish: lemon zest or slice

1. Pour the rum, lemon juice, sugar syrup, and egg white (if using) into a shaker without ice.
2. Dry shake vigorously for 10 seconds to emulsify.
3. Add ice and shake again energetically.
4. Strain into an old fashioned or cocktail glass.
5. Garnish with a lemon slice or zest.

- Swap the amber rum for spiced rum for more character.
- Add a few drops of aromatic bitters for extra complexity.
- Use aquafaba (chickpea brine) instead of egg white for a vegan version.
