Ingredients

  • 6 oz butterfly pea flower tea, cooled (steep 1 tbsp dried flowers in hot water 5 min)
  • 1 oz simple syrup
  • 2 oz fresh lemon juice (served separately or added at the table)
  • Ice cubes
  • Lemon wheel and blueberries, for garnish
  • Star-shaped ice cubes (optional, for extra flair)

Step-by-Step Instructions

  1. 1

    Prepare the glass

    Brew the butterfly pea flower tea: steep 1 tablespoon of dried flowers in 1 cup of hot water for 5 minutes. Strain and let cool completely.

  2. 2

    Build the drink

    Fill a tall glass with ice cubes (use star-shaped ice if you have them).

  3. 3

    Add the finishing touch

    Add simple syrup to the glass and stir.

    Garnish & serve

    Pour the cooled butterfly pea flower tea over the ice — it will be a vivid, deep blue.

  5. 5

    Garnish & serve

    Garnish with a lemon wheel and blueberries.

  6. 6

    Garnish & serve

    Serve the lemon juice on the side in a small pitcher or shot glass.

  7. 7

    Garnish & serve

    At the table, pour the lemon juice in and watch the magic happen — the drink transforms from blue to purple to pink as you stir.

Recipe Tips

  • For the most dramatic color change, make sure the tea is fully cooled before serving — warm tea dilutes the effect.
  • Butterfly pea flower tea is widely available on Amazon and at health food stores.
  • For a party, set up a 'color change station' where guests add their own lemon juice — it becomes an interactive experience.

Make It Your Own

For a crowd: Prepare red and blue components separately. Set up a simple assembly line with clear cups, ice, and garnish so each guest gets a fresh patriotic pour.

Easy swaps: Use blueberries, blue raspberry, or butterfly pea for blue tones. Use strawberries, watermelon, grenadine, or cherry for red tones.

Frequently Asked Questions

How do I keep layers separate?

Use plenty of ice and pour the denser, sweeter components slowly over the back of a spoon.
