Borinquen Rum Cocktail

Pro tips

• Fresh lime and orange juice are essential—use citrus juice within 4 hours of squeezing for maximum brightness.
• Chill your glass beforehand to keep the drink cold longer without over-dilution.
• Float the 151 Proof Rum on top by pouring slowly over the back of a bar spoon for visual appeal and separate sips of heat.
• Taste for balance; if too tart, add 1/2 tsp more passion fruit syrup rather than sugar.

Substitutions

• Mr. Boston Rum → Bacardi or Appleton Estate light rum (similar proof and flavor profile)
• Passion Fruit Syrup → passion fruit juice or guava syrup (may need to reduce to 3/4 tbsp for balance)
• 151 Proof Rum → 1/2 tsp Bacardi 151 or omit entirely for a lighter drink

Storage & make-ahead

Can I make this cocktail without passion fruit syrup?

Yes. Substitute with passion fruit juice, guava syrup, or mango nectar (1 tbsp), though the drink will taste less concentrated.

What does the 151 Proof Rum float do?

It adds alcohol intensity and a warming finish. You can reduce it to 1/2 tsp or omit it for a lower-proof version.

Should this be shaken or stirred?

Shake vigorously with ice to chill and dilute slightly; strain into a rocks glass over fresh ice or up into a coupe.

Can I batch this cocktail?

Yes. Multiply the ingredients and store in a bottle; shake with ice and pour when ready. Best consumed within 24 hours.

What rum brands work best?

Aged light or gold rums (Bacardi, Appleton) work well. Avoid dark rums unless you prefer a heavier profile.
