Tips & Variations:
- Layered look: Pour lemonade into a glass first, then slowly add the blue tea on top for a layered blue-to-pink gradient before stirring.
- Cocktail version: Swap in gin or vodka for an adult "potion" drink — the color-change effect works exactly the same.
- Make it a mocktail bar: Set out the blue tea, lemon wedges, and a few fruit syrups, and let people mix their own color at a party.
- Storage: The unflavored blue tea keeps in the fridge up to 5 days. Add lemon fresh, right before serving, since the color shift happens immediately.
