Butterfly Pea Lemonade Recipe
Make Butterfly Pea Lemonade Recipe for a color-changing, chilled citrus drink—simple, stunning, and ready in about 25 minutes.
Ingredients
- 2 cups (480 ml) water, just off the boil (about 200°F / 93°C)
- 2 tablespoons (about 4 g) dried butterfly pea flowers (or 2 butterfly pea tea bags)
- 1 cup (240 ml) freshly squeezed lemon juice (from about 5–6 medium lemons), strained
- 1/2 cup (100 g) granulated sugar
- 1/4 cup (60 ml) simple syrup, chilled (optional, for adjusting sweetness)
- 2 cups (480 ml) cold water, filtered
- 2 cups (about 240 g) ice cubes, plus more for serving
- 1/8 teaspoon fine sea salt
- 1 lemon, thinly sliced into rounds, for garnish
- 8–10 fresh mint leaves, lightly bruised, for garnish
- Lemon wedges, for serving (optional)
- Additional ice cubes, for serving
Instructions
Step 1: Steep and sweeten the butterfly pea tea
Heat two cups of water until just off the boil, then pour it over the dried butterfly pea flowers placed in a clear heatproof measuring jug. Let the flowers steep 7–10 minutes, stirring once or twice until the water becomes a deep, vibrant blue. Strain the tea through a fine-mesh sieve back into the jug, discard the spent flowers, then while still warm stir in the granulated sugar and a pinch of fine sea salt until fully dissolved and the liquid looks perfectly clear and jewel-toned. Let the sweetened tea cool to room temperature, then chill until very cold.
Step 2: Juice and strain the lemons
Squeeze fresh lemons until you have a cup of bright, tangy lemon juice, then strain it through a fine sieve into a small chilled glass jug to remove seeds and excess pulp. Keep the lemon juice covered and cold in the refrigerator while the tea chills; its pale, citric yellow will be the dramatic color-change trigger when it meets the blue tea.
Step 3: Build the chilled base in a pitcher
Pour the thoroughly chilled butterfly pea tea into a large clear glass pitcher, add the cold filtered water to balance intensity, then add plenty of ice and stir briefly to bring everything down to refrigerator temperature. The mixture at this stage should remain a saturated, translucent sapphire blue with sparkling ice facets and tiny condensation beads on the outer glass.
Step 4: Add lemon, watch the color transform, and adjust sweetness
Slowly stream the cold, strained lemon juice into the iced blue pitcher while gently stirring; watch the chemistry and color morph from deep blue to vibrant purple and then magenta as acidity shifts the pigment. Taste and, if needed, stir in up to a quarter cup of chilled simple syrup a tablespoon at a time until the sweetness is balanced. The final liquid should be glossy, evenly colored, and clear—no sugar grit, with cold ice pockets softening the hue.
Step 5: Serve cold with lemon and mint garnish
Fill individual clear glasses with fresh ice, pour the butterfly pea lemonade so each glass shows the clean, saturated purple, then finish with a thin lemon round on the rim and a couple of lightly bruised mint leaves tucked into the ice. Serve immediately while very cold; the glasses should show delicate condensation, crisp ice geometry, and bright citrus/mint accents.
Notes
- Steep butterfly pea flowers 7–10 minutes for best color without bitterness.
- Use freshly squeezed and strained lemon juice for brightest flavor and color change.
- Chill the tea thoroughly before adding lemon to preserve clarity and color.
- Make simple syrup ahead to quickly adjust sweetness without graininess.
- Store in a sealed glass container and consume within 48 hours for best freshness.
