Borinquen Rum Cocktail

Pro tips

• Float the 151 proof rum gently over the back of a bar spoon to layer it on top without mixing; sip through the float for full impact.
• Use fresh lime and orange juice—bottled or concentrate will muddy the bright citrus and passion fruit balance.
• Chill your glass before mixing to reduce dilution from melting ice.
• Stir or shake vigorously with ice for 10–15 seconds to chill and slightly dilute, softening the high alcohol content.

Substitutions

• Passion fruit syrup → passion fruit juice (1.5 oz, reduce other citrus slightly) or passion fruit purée with simple syrup
• Light rum → white rum or silver rum (similar proof and flavor profile)
• 151 proof rum → overproof rum or dark rum (adjust intensity to taste; 151 is traditional)

Storage & make-ahead

Cocktails are best served fresh. Pre-batch the rum, passion fruit, and citrus in a bottle for up to 24 hours; add ice and 151 float when serving.

What does passion fruit syrup taste like?

Passion fruit syrup is tart, slightly sweet, and tropical with floral notes. It adds brightness and depth without overwhelming the cocktail.

Can I use fresh passion fruit instead of syrup?

Fresh passion fruit pulp requires extra prep and adds acidity; use 1–1.5 tbsp pulp plus 0.5 tbsp simple syrup, then taste and adjust.

Why use 151 proof rum?

151 proof rum adds alcohol warmth and intensity as a float, preventing dilution and creating a signature spiced finish.

Should I chill the glass?

Yes, chill with ice or cold water for 1–2 minutes before serving to keep the drink cold longer without over-dilution.

What ice works best?

Large cubes or crushed ice; large cubes dilute slower and suit sipping, while crushed ice chills faster for a lighter texture.
