# What You Need:
→ Blackberry Syrup
01 - 1/2 cup fresh blackberries
02 - 1/4 cup granulated sugar
03 - 1/4 cup water
04 - 1 teaspoon lemon juice
→ Charcoal Base
05 - 1/4 teaspoon food-grade activated charcoal powder
06 - 1 cup cold sparkling water
07 - 1 tablespoon fresh lime juice
08 - 1 teaspoon agave syrup (or simple syrup), to taste
→ Garnish & Assembly
09 - Crushed ice
10 - Blackberries, for garnish
11 - Lemon or lime wheels, for garnish
12 - Fresh mint sprigs (optional)
# Steps:
01 - Combine blackberries, sugar, and water in a small saucepan over medium heat. Gently mash berries and simmer for 3 to 4 minutes until syrup thickens. Remove from heat, stir in lemon juice, then strain through a fine mesh sieve, discarding solids. Allow syrup to cool.
02 - In a small pitcher, stir together cold sparkling water, activated charcoal, fresh lime juice, and agave syrup until charcoal fully dissolves forming an inky black mixture.
03 - Fill two tall glasses three-quarters full with crushed ice. Pour charcoal base evenly over ice. Slowly layer 2 tablespoons of blackberry syrup onto each glass by pouring over the back of a spoon to create distinct layers.
04 - Top with fresh blackberries, lemon or lime wheels, and optional fresh mint sprigs. Serve immediately to preserve layering and freshness.
