BUTTERFLY PEA

This is a flower whose name carries its own passport. The species epithet ternatea points to Ternate, a small volcanic island in the Moluccas of Indonesia, from where European botanists first catalogued it — and across equatorial Asia it has been woven into kitchens for centuries. [source] In Thailand the dried petals become nam dok anchan, a deep-blue tea served sweetened with honey and lemon, the lemon tipping the cup from blue to purple. [source] In Malaysia the same blue stains the rice of nasi kerabu, and across the region the flower has coloured glutinous rice and sweets for generations. [source] What looks like a modern Instagram trick is in truth an old pigment, freshly rediscovered — the original colour-changing magic, painted in petals.

Reach for Butterfly Pea when you want a gin that performs. A full sachet steeped in your spirit pulls a deep indigo-to-purple; a partial amount gives a softer wash of colour while keeping the flower's mild, earthy note in the background. [source] It adds almost no competing flavour, so it sits behind your juniper rather than fighting it. Pair it with Lemon Myrtle or a twist of citrus at serving time — that is what triggers the blue-to-pink reveal in the glass.

Butterfly Pea is a colour botanical, not an aroma one — its character is pigment chemistry. The blue comes from ternatins, a family of polyacylated delphinidin triglucosides built on a delphinidin-3-glucoside core. [source] These anthocyanins are pH-responsive: violet-blue around pH 3.2–5.2, light blue through neutral, and red below pH 3.2 — so a squeeze of acidic citrus pulls the liquid from blue toward purple-pink. [source] The pigment is stable to around 60–70°C but light-sensitive, which is why you steep in cool spirit and keep the bottle out of the sun. [source] The flavour itself stays mild and earthy — closer to a fine green tea than to anything sweet. [source]
