Butterfly pea tea is a herbal, caffeine-free beverage that is brewed from the leaves or whole flowers of the Clitoria ternatea plant. It’s also known as aprajita in Hindi and Bengali, or Shankhpushpi or Shankhapushpam in Sanskrit, Tamil and Telugu. You've seen it on your feed as the reason behind the viral colour-changing drink that changes from an impossibly blue drink to purple the second someone squeezes in a lemon. This article explains why it's more than just a pretty trick.
Butterfly pea flower is native to Asia, easily recognised by its vibrant blue colour, although there are other variants. It has a high concentration of antioxidant compounds called anthocyanins — thus, it not only looks good, but is also good for your body. Known primarily for the blue pea tea or blue tea that it produces, it has been used in countless dishes, be it sweet, savoury or in drinks. As for non-edible uses, it has been an active ingredient in Ayurveda, working as a natural fabric dye for decades.
In Thailand, it's enjoyed as an after-dinner drink called nam doc anchan, a blend of butterfly pea tea, sweetener, and lime juice. Ground into powder, it becomes what some call blue matcha. It's rich in antioxidants and has been linked by medical establishments to benefits like blood sugar management, hair and skin health, and weight management – though it's the colour-changing kitchen magic that's made it into a viral obsession.
This is the classic butterfly pea flower tea recipe that barely needs much effort. Steep dried or fresh butterfly pea flowers in hot water, press them against the cup to extract colour, strain, add sweetener and ice. This is where it gets interesting – squeeze in lime juice right before serving to watch the colour shift and fascinate the one you are serving. Serve in a clear glass to show off the colours.
Tips:
Steep for 5-10 minutes (or longer) to intensify the deep blue colour.
Use filtered water, as highly acidic water can dull the blue colour prematurely.
Add citrus gradually (drop by drop) if you want a layered gradient instead of instant purple.
Brew a strong batch of butterfly pea tea and use it as the liquid base for the usual milk pudding or panna cotta. You get a striking blue-purple dessert that needs zero artificial colouring. The butterfly pea tea’s mild, earthy flavour is subtle enough not to overwhelm the vanilla or coconut flavours, making it the perfect dish with milk flavours.
Tips:
Use a concentrated brew so the colour doesn’t fade when mixed with milk or cream.
Avoid strongly acidic ingredients (like fruit purées) during mixing, as they can shift the colour from blue to purple.
Heat on a low flame, as the high heat can slightly dull the pigments.
To make blue rice, steep the butterfly pea flowers in hot water to extract their colour. Then add this coloured water directly into a rice cooker along with water and optional lemongrass, and cook until done. You can also cook the rice in a pot, on the stove, with the blue liquid. The rice turns a pastel blue to a bluish-purple colour. In Malaysian cuisine, a version of this called nasi kerabu is a well-known dish served with coconut milk and curry.
Tips:
Use a strong infusion (double flowers) to ensure the colour survives cooking.
The colour appears more vivid in light-coloured, non-sticky rice.
You can add a squeeze of lime after cooking to shift parts of the rice to purple tones.
Brew butterfly pea tea, sweeten it, and pour it over cooked tapioca pearls and ice. Add coconut milk or regular milk for a layered effect. You can use blue tea as a base for ice cubes in cocktails or as a colour additive in drinks – the same logic applies here. The blue tea poured over white milk creates a gradient that looks almost too good to stir.
Tips:
Use rock sugar to sweeten the butterfly pea tea.
Consider adding more flavours like using a creamy coconut milk, honey, or vanilla essence, and serve it warm or chilled.
Use ice cubes made from butterfly pea tea to enhance colour without dilution.
Make pancakes the regular way, but just substitute part of the liquid in your pancake batter with a concentrated butterfly pea tea infusion. You can also use butterfly pea tea powder instead of brewing the tea. The batter will develop a dusky blue hue, cooking into lilac-grey pancakes. You can use the same technique that carries over seamlessly to cakes, cookies, and icings.
Tips:
Strain the tea well to avoid any petal residue affecting the batter texture. Avoid adding acidic ingredients (like lemon or buttermilk) to the batter if you want to preserve the blue tone.
Pair with light-coloured toppings (cream, yoghurt, coconut) to highlight the subtle lilac hues.
You can make a wide variety of cakes with just a few teaspoons of butterfly pea tea powder. Add it to your muffin or cake batter, buttercream, or glaze. If making a single loaf cake, make sure to add it to the lemon glaze, as the icing will turn from blue to pink right in front of your guests.
Tips:
Use powder for frosting because it gives a more vibrant colour than liquid tea.
Keep the batter ingredients low in acidity – no buttermilk or yoghurt – to maintain a blue hue before glazing.
Add citrus glaze last as the anthocyanins react instantly to pH, creating the colour shift effect.
Butterfly pea tea is one of those rare ingredients that earns its place both on a wellness shelf and in a proper recipe book. You can brew it, bake with it, or turn it into a creative exercise by using butterfly pea tea in different recipes. Whether you're after its health-boosting properties, the aesthetics of it or just want something different for the weekend, this is one pantry addition that genuinely delivers.
