If you have ever walked down a street in Bangkok, Chiang Mai, or any Thai night market, you have seen it — a tall plastic bag of blazing orange liquid, ice-packed, with a straw poking out, condensed milk swirling in slow white ribbons through the colour. That is cha yen, and it is one of the most visually striking teas on Earth.
The orange colour is not artificial trickery. Traditional Thai tea blends use a combination of Ceylon black tea, star anise, crushed tamarind seed, and sometimes food colouring to achieve that sunset hue. The original colour, without additives, is a deep amber-orange from the tea and spices alone.
Thailand's tea culture was heavily influenced by Chinese immigrants, particularly the Yunnanese and Teochew communities who settled in northern and central Thailand over centuries. Cha yen is a distinctly Thai adaptation — taking strong Chinese-style tea and reinventing it with tropical sweetness and dairy richness.
Method
Step 1. Bring 2 cups of water to a boil. Add the Thai tea mix (or Ceylon tea) and star anise. Reduce heat and simmer for 5 minutes.
Step 2. Strain into a heatproof jug, pressing the leaves to extract maximum flavour. The liquid should be very dark and very strong.
Step 3. Stir in the sweetened condensed milk while the tea is still hot. Add vanilla extract if using.
Step 4. Let cool to room temperature, then chill in the fridge for at least 30 minutes.
Step 5. Fill tall glasses with ice. Pour the chilled tea over the ice until glasses are three-quarters full.
Step 6. Slowly pour evaporated milk over the back of a spoon so it floats on top in a white layer. Serve with a long straw — stir before drinking.
Notes
- Thai tea mix (such as the Chatramue/Number One brand with the orange label) is available at Asian grocery stores and online. If unavailable, use a strong-brewed Ceylon or Assam tea with a pinch of ground star anise.
- For a less sweet version, use half the condensed milk and substitute fresh whole milk for the evaporated milk.
- In Thailand, cha yen is often sold from street carts that brew the tea in enormous kettles, running through a cloth filter multiple times for maximum strength.
The orange tea of Thailand is not subtle. It does not whisper. It is monsoon-season sweetness in a glass, and it does not apologise for that.
