This vibrant butterfly pea flower tea latte transforms any ordinary day into something magical. The stunning blue hue that shifts to purple with just a drop of lemon juice makes this drink not just delicious but a visual spectacle worth sharing on social media.
I first discovered butterfly pea flower tea during a trip to Thailand and became instantly mesmerized by its color changing properties. After perfecting this latte version at home, it has become my signature drink whenever friends visit they always request "that magical blue tea" before anything else.
Ingredients
- Dried butterfly pea flowers: Provide the natural vibrant blue color. Look for organic varieties for the cleanest flavor and most vivid color.
- Hot water: Should be just off the boil to extract maximum color without bitterness.
- Milk: Creates the creamy latte effect. Full fat dairy gives the richest result but plant based alternatives like coconut milk complement the floral notes beautifully.
- Honey or sweetener: Balances the subtle earthiness of the tea. Raw honey works wonderfully but maple syrup offers a distinct complementary flavor profile.
- Ice cubes: Keep everything refreshingly cold. Consider making ice cubes from the tea itself to prevent dilution.
- Lemon juice: Triggers the magical color transformation from blue to purple. Fresh squeezed provides the best effect and flavor.
Step-by-Step Instructions
- Brewing the Tea:
- Steep the butterfly pea flowers in hot water for exactly 5 to 7 minutes. Any less and the color will be too weak; any longer and subtle bitterness may develop. The water should transform into a deep indigo blue as it extracts both color and flavor compounds from the flowers. For maximum visual impact, use a clear glass pot for brewing.
- Sweetening:
- While the tea is still warm but not hot, incorporate your chosen sweetener. The slight warmth helps it dissolve completely without diluting the color. Stir gently in one direction to maintain the clarity of the tea. Taste and adjust sweetness level as butterfly pea flower tea has a very subtle earthy flavor that should remain detectable.
- Creating Foam:
- Properly frothing the milk creates that luxurious latte texture. Cold frothing works differently than hot frothing but is still effective. If using a jar method, shake vigorously for at least 45 seconds until the volume nearly doubles. Let it rest for 30 seconds before pouring to allow bubbles to stabilize.
- Layering:
- The magic happens during this step. Fill your glass with ice first, then pour the blue tea slowly over the back of a spoon to create a gentle flow. When adding the frothed milk, again use the back of a spoon and pour slowly along the inside edge of the glass to create distinct layers of blue and white.
- Color Transformation:
- This optional step creates a stunning purple ombré effect. Add the lemon juice last, drizzling it slowly on top. Watch as the acidity changes the pH of the tea, transforming the blue anthocyanins to purple before your eyes. This chemical reaction creates a beautiful gradient from blue at the bottom to purple at the top.

The most fascinating aspect of this drink for me is the science behind the color change. I once served this at a family gathering and my young niece thought I was performing magic when I added the lemon juice. That moment sparked her interest in both cooking and science experiments which makes this recipe particularly special to me.
Storage and Preparation
The brewed butterfly pea tea can be stored in the refrigerator for up to three days in an airtight container. This makes it perfect for advance preparation when entertaining. The color remains stable when refrigerated but will slowly fade if exposed to direct sunlight. For best results, assemble the final latte just before serving to maintain the dramatic layered effect and enjoy the fresh milk foam.

Creative Variations
This versatile recipe welcomes personalization. Add a sprig of fresh lavender or a few drops of vanilla extract to enhance the floral notes. For a tropical twist, replace half the water with coconut water and use coconut milk for the latte portion. During summer months, freeze butterfly pea tea in ice cube trays with edible flowers for stunning ice cubes that continue to release color as they melt.
Health Benefits
Butterfly pea flower has been used in traditional Ayurvedic medicine for centuries. Beyond its stunning color, it contains anthocyanins that function as powerful antioxidants. Regular consumption may support improved memory function and reduced inflammation. The tea is naturally caffeine free, making it suitable for evening enjoyment without disrupting sleep patterns. When unsweetened, it's virtually calorie free while still delivering visual impact and subtle flavor.
Serving Suggestions
Present this latte in clear glassware to showcase its beautiful color gradients. For special occasions, rim the glass with a touch of honey and dip in dried butterfly pea flowers for an elegant presentation. This drink pairs wonderfully with light desserts like coconut panna cotta or lemon shortbread. For brunch gatherings, serve alongside tropical fruit platters where the blue-purple tones create stunning visual contrast.
