What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 2 tbsp dried butterfly pea flowers
  • 480 ml hot water
  • 60 ml fresh lemon juice
  • 3 tbsp simple syrup
  • 2 cups ice cubes

Step by step instructions

Step 1: Brew the Butterfly Pea Flower Tea

Place the dried butterfly pea flowers in a heatproof pitcher and pour hot water over them. Steep for 5 minutes until the water turns a deep vivid indigo blue, then strain out the flowers and allow the tea to cool completely.

Step 2: Prepare the Sweetened Lemon Juice

Combine fresh lemon juice and simple syrup in a small bowl and stir well until fully blended. Keep this mixture separate from the blue tea to preserve the dramatic color-change moment.

Step 3: Create the Color Change Effect

Fill two glasses generously with ice cubes and pour the deep blue butterfly pea flower tea over the ice. Slowly pour the sweetened lemon juice into each glass and watch the magical transformation from blue to purple as the citric acid reacts with the anthocyanins in the tea.
