Frozen Berkeley

Pro tips

• Use fresh lemon juice, not bottled — the acidity is crucial for balancing the rum, brandy, and sweetness of passion fruit syrup.
• If blending, use about 1 cup of ice and blend until smooth and slushy; over-blending dilutes the drink.
• Chill your serving glass beforehand to maintain the frozen texture longer.
• Taste before serving and adjust passion fruit syrup or lemon juice to your preference — passion fruit syrups vary in sweetness.

Substitutions

• Light Rum → White rum or aged rum (note: aged rum adds depth but may dominate the fruit flavors)
• Brandy → Cognac or Armagnac (note: higher quality spirits enhance complexity)
• Passion Fruit Syrup → Passion fruit juice or purée diluted with simple syrup (note: use less volume and adjust to taste)

Equipment

blender (if making frozen version) · cocktail shaker (if making shaken version) · bar strainer

Can I make a Frozen Berkeley without an ice blender?

Yes. Shake all ingredients vigorously with ice cubes in a cocktail shaker, then strain into a chilled coupe or rocks glass filled with crushed ice.

What type of passion fruit syrup should I use?

Use a pure passion fruit syrup or cordial. Homemade or commercial brands like Monin or Small Hand Foods work well; adjust sweetness to taste.

Can I substitute the brandy?

Cognac, Armagnac, or even a dry fruit brandy work as substitutes. Avoid flavored brandies as they may clash with passion fruit.

Is this drink supposed to be frozen or chilled?

Frozen (blended with ice) is traditional, but it can be served as a chilled, shaken cocktail over ice if preferred.

What is the origin of the Frozen Berkeley?

The Frozen Berkeley is a vintage tropical cocktail, likely from mid-20th century classic cocktail repertoire, though specific origin details are limited.
