Want to see a magic trick? Add a squeeze of lemon to this juicy blue raspberry blend and watch it go from indigo to violet – no enchantments or pixie dust needed. The secret ingredient? Butterfly pea flower – a unique plant from Southeast Asia that turns tea blue naturally thanks to its bright azure petals. Spritz in some lemon and a drizzle of honey for the ultimate nightcap. Or serve it iced for a refreshing berry-packed tonic. With its fun colour-changing powers, it’s like a mood ring in your mug.
