Butterfly pea tea, also called anchan tea, is a caffeine-free herbal drink made from butterfly pea flowers. It has a mild, earthy taste and is known for its calming and antioxidant benefits. The tea turns purple when you add lemon or lime.
Why does it change color?
After steeping, the blue tea turns purple when lime or lemon is added because the acidity lowers the pH level, causing the anthocyanin pigments in the flowers to react and shift color.
That’s what makes the tea turn purple, and sometimes pink if the acid level is high enough!
