How does the colour change actually work?

Butterfly pea flower contains anthocyanin pigments that are pH-sensitive. In neutral water the tea is a deep indigo blue; when you add something acidic — lemon or lime juice — the lower pH shifts the pigment to purple, then pink. It's real, harmless food chemistry, and pouring the citrus slowly lets you show the gradient mid-transformation.

What does it taste like?

Butterfly pea tea itself is very mild and earthy-floral, almost neutral — the flavour comes from what you build around it (honey, citrus, soda or lemonade). That's part of its appeal: it delivers dramatic colour without dictating taste, so you can flavour it however you like.

Where do I get butterfly pea flowers?

Dried butterfly pea flowers are widely available online and in tea and Asian grocery shops, sold loose or as tea bags. Steep them strongly in hot water and chill — a concentrated brew gives the most vivid blue and the most dramatic change.
