Frozen Berkeley

Pro tips

• Use fresh lemon juice, not bottled, for brighter acidity that cuts through the sweetness of passion fruit syrup.
• Chill your glass beforehand to keep the drink cold longer without over-diluting.
• Balance the passion fruit syrup carefully—start with the tablespoon measure and taste before adding more, as homemade syrups vary in intensity.
• Blend or shake for a full 10–15 seconds to achieve a proper slushy consistency if serving frozen.

Substitutions

• Mr. Boston Rum → Bacardi or other light rum (neutral flavor, similar proof)
• Mr. Boston Five Star Brandy → cognac or other brandy (richer flavor, no functional change)
• Passion Fruit Syrup → passion fruit juice concentrate or fresh strained pulp (adjust to taste)

Storage & make-ahead

Cocktails are best served immediately. Pre-batch the syrup, rum, and brandy in a pitcher and refrigerate up to 24 hours; add fresh lemon juice and blend with ice just before serving.

What does a Frozen Berkeley taste like?

A Frozen Berkeley tastes tropical and tart, with sweet passion fruit notes balanced by bright lemon acidity and warm rum and brandy undertones.

Should this cocktail be blended with ice?

Yes, blend all ingredients with ice until slushy for the proper frozen texture, or shake vigorously with ice and strain into a crushed-ice-filled glass.

Can I make a Frozen Berkeley without passion fruit syrup?

Passion fruit juice concentrate or fresh passion fruit pulp strained works as a substitute, though the flavor profile will shift slightly.

What glassware is best for serving?

Serve in a chilled coupe, rocks glass filled with crushed ice, or frozen cocktail glass for optimal presentation and temperature retention.
