Halloween Blackberry Witch Fizz

By Kaya ·

A Blackberry Witch Fizz is a gin cocktail of muddled blackberries, 2 oz gin, lemon juice and simple syrup, topped with ginger beer for a deep purple drink. It takes about 10 minutes and has roughly 236 kcal and 10% ABV per drink.

This Halloween blackberry witch fizz gets its deep purple color from muddled berries. Ginger beer makes it lively and a rosemary sprig gives the glass a little haunted-forest character. The recipe makes one drink; build a tray of glasses by muddling berries and lemon in each, then add the ginger beer just before serving.

METHOD

How to make it

  1. Muddle five blackberries with the lemon juice and syrup in a shaker. Add gin and ice, then shake for 10 seconds.
  2. Double-strain into an ice-filled highball glass if you prefer a clear finish; leave the seeds in for a more rustic look.
  3. Top slowly with ginger beer and stir once. Garnish with two blackberries and rosemary.

Recipe notes

Prepare one serving at a time. Add sparkling ingredients only when ready to serve.

Common questions

How do I adjust the sweetness?

Taste before topping up: blackberries vary in sweetness, so add a little more syrup for tart fruit.

Is there an alcohol-free version?

Yes. Replace the gin with 2 oz chilled sparkling water and keep the ginger beer. Ginger beer is usually nonalcoholic, but check the label if that matters to your guests.

Can I make it ahead for a party?

Muddle the berries and mix the gin, lemon and syrup ahead, then refrigerate. Add ice and ginger beer to each glass at serving time.
