Tips & Notes

Pro tips

Use fresh lemon juice, not bottled—the acidity and brightness are crucial to balancing the rum and brandy.
Chill your serving glass in the freezer for 5 minutes before pouring to keep the drink colder longer.
Blend until smooth and slushy, not watery; add ice incrementally if the mixture becomes too thin.
Taste as you blend—passion fruit syrup varies in intensity, so adjust sweetness with extra lemon juice if needed.

Substitutions

Light Rum → white rum or silver rum (same proof and dryness)
Brandy → cognac or pisco (adds depth; use same quantity)
Passion Fruit Syrup → fresh passion fruit pulp strained + 1 tsp simple syrup (more intense flavor)

Storage & make-ahead

Serve immediately after blending. Unmixed ingredients keep refrigerated for up to 4 hours; re-blend with fresh ice before serving.

Equipment

blender · cocktail shaker (optional, for non-frozen variation)

Common Questions

Can I make the Frozen Berkeley without a blender?

You'll need a blender to achieve the proper frozen texture. Without one, stir ingredients with ice in a cocktail shaker and serve over crushed ice for a similar effect.

What type of passion fruit syrup should I use?

Use a commercial passion fruit syrup or bar syrup. If unavailable, substitute with passion fruit juice concentrate diluted with simple syrup in a 1:1 ratio.
