This wicked blackberry fizz mocktail combines juicy blackberries, fresh lime juice, and sparkling water for a fruity, lightly tart drink. Its rich berry color makes it a fun alcohol-free choice for Halloween, without needing food coloring.
Make two glasses in about 10 minutes. Taste before adding simple syrup—ripe blackberries may need only a little sweetness to balance the lime.
Makes: 2 servings
Preparation time: About 10 minutes
Prefer less sweetness? Leave out the simple syrup or use just a small amount. Taste your berries first, because their sweetness can vary.
Want a sharper finish? Add extra lime juice a teaspoon at a time, tasting as you go.
Prefer a lighter drink? Add a little more sparkling water to each glass.
Like some fruit pulp? Skip straining and divide the crushed berry mixture between the glasses. The drink will have more texture and contain blackberry seeds.
Want a Halloween touch? Serve with black-and-white paper straws and place small decorative pumpkins beside the glasses. Keep plastic spiders and other decorations on the table, outside the drinks.
Prepare the strained blackberry juice, lime juice, and optional simple syrup ahead of time. Keep the mixture covered in the refrigerator and use it the next day.
Stir before dividing between glasses. Add ice, sparkling water, and garnishes just before serving so the drink stays fizzy and isn’t diluted by melting ice.
Can I use frozen blackberries?
Yes. Thaw unsweetened frozen blackberries before crushing them, and include the juice they release as they thaw. Strain and mix as directed.
Do I have to strain the blackberries?
No. Straining gives you a smoother drink without seeds. If you enjoy a more rustic texture, leave the crushed berries in.
Can I use bottled lime juice?
Yes. Start with the same amount, then adjust to taste. Fresh lime juice gives a fresher citrus flavor, but bottled juice is a convenient option.
Can I use tonic water instead of sparkling water?
Yes, although it will change the flavor. Tonic water adds bitterness and usually sweetness, so leave out the simple syrup initially and taste before adding any.
Will the drink be dark purple?
The shade depends on your blackberries and how much sparkling water you add. Expect a purple-to-reddish berry color that becomes lighter as you dilute it. No food coloring is needed.
