Nam dok anchan (butterfly pea lemonade)
Vines of butterfly pea climb fences in gardens all over Thailand, and cafés from Bangkok to Krabi serve the flowers as an iced drink that changes colour at the table. The tea itself is mild and earthy, blue as ink; stirring in lime juice turns it violet and makes it tangy, which children love to watch. Chef's tip: the common mistake is mixing the lime in beforehand; serve the blue tea and lime separately so the colour change happens in the glass.
