Frozen Berkeley

Pro tips

• Blend all ingredients with ice until completely smooth to avoid separation and ensure a uniform frozen texture.
• Use fresh lemon juice rather than bottled for brighter, more balanced acidity against the sweetness of passion fruit syrup.
• Chill your serving glass in the freezer for 5 minutes before pouring to keep the cocktail colder longer.

Substitutions

• Old Mr. Boston Five Star Brandy → cognac or VS brandy (similar body, slightly more refined)
• Passion Fruit Syrup → passion fruit nectar or frozen passion fruit puree (reduce quantity by 10–15% to avoid oversweetening)
• Lemon Juice → fresh lime juice (shifts flavor toward citrus-forward, slightly more tropical)

Do I need a blender to make a Frozen Berkeley?

Yes, a blender is essential to achieve the frozen texture. Add ice, spirits, syrup, and juice, then blend until smooth.

Can I make this cocktail without passion fruit syrup?

Passion fruit syrup is a core ingredient. You can substitute passion fruit nectar or puree (use slightly less), but the flavor profile will differ.

How much ice should I use?

Use about 1 cup of ice or enough to fill your blender halfway. Adjust to reach your preferred consistency—more ice for thicker, less for smoother.

Can I batch this cocktail in advance?

Blend and serve immediately for best results. Pre-mixing the spirits, syrup, and juice is possible, but blend with fresh ice just before serving.
