Thai Iced Tea (ชาไทย)

Why Your Thai Tea Is Orange

The colour is the dish's best story: it's added food colouring, and the reason is logistics. Once milk goes in, iced tea and iced coffee both turn beige — so shops coloured the tea orange so staff could tell ชาเย็น from โอเลี้ยง apart at a glance. There's an older theory too: servants re-steeping spent leaves until the colour faded, then restoring it with roasted tamarind seed. Either way, the orange is practical, not natural — a fact most western recipes never mention.

The tea itself is the real thing: a spiced black-tea blend — Ceylon leaves cut with star anise and cardamom — the famous Cha Tra Mue (Number One) brand. Red pack is fragrant; gold pack is stronger and pricier. And the naming is a national argument: ชาเย็น means the classic iced version with condensed milk, ชานม is milk tea, ชาดำ/ชาใส means no milk. A Thai beverage supplier's FAQ is literally titled "Ordered cha yen, why did I get cha nom?" — the country argues about this over the counter every day.

On Pantip the beginner's struggle is the same thread every year: "three days of brewing Cha Tra Mue and it's still not good." The answer is never the brand. It's the steep, the sweetness before the ice, and the pour.

The Recipe (Rin's Cookbook home method — 2 glasses)

The southern (ปักษ์ใต้) blend, from Wongnai's ten-recipe roundup: 1 tbsp fragrant tea + 1 tbsp Thai tea + 1 tbsp Ceylon tea, 200 ml very hot water, 1 tsp sugar, 2 tbsp condensed milk, ice, 50 ml fresh or evaporated milk.

The Method

1. Steep strong. Very hot water over the tea powder, stirred, left 3–5 minutes — long enough for the spices to come out, not so long it turns harsh. Strain completely.
2. Sweeten warm. Condensed milk and sugar stirred in while the tea is still warm, until dissolved. The tea must be sweet and strong before the ice, because the ice will dilute both — this is the Pantip three-day lesson.
3. Ice first. Glasses filled to the top, tea poured over, room left at the rim.
4. The pour. Evaporated milk poured slowly over the top so it streaks down through the tea — the layered look is the signature. Serve unstirred; each drinker stirs their own.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Weak brew. The Pantip three-day complaint: too little tea, too short a steep, and the ice finishes the job. Brew it strong and sweet before any ice exists.
• Everything stirred in. The evaporated milk goes over the top and streaks down. Stirred-in is a different, flatter drink.
• Bubble-tea treatment. Fruit syrups and tapioca pearls are a different drink from a different country. This one is tea, milk, sugar, ice.
• Fear of the colour. The orange is added colouring, documented and traditional — it's how the drink tells itself apart from iced coffee. No need to apologise for it.
• Generic black tea. A plain English Breakfast bag makes brown sweet milk. The spiced Thai blend — star anise, cardamom — is the flavour.

UK Ingredient Notes

• Cha Tra Mue (Number One) Thai tea: red and gold packs in Asian grocers and online — red for fragrance, gold for strength. This is the one ingredient that matters.
• Condensed and evaporated milk: any supermarket — Carnation is the Pantip thread's own choice.
• If you can't get Cha Tra Mue, a Ceylon black tea with a pinch of crushed star anise and cardamom gets close; an English Breakfast bag doesn't.
• Ice: more than feels sensible — the dilution is part of the recipe, so the pre-ice sweetness has to be real.
• Batch version: the litre recipe scales cleanly — 60 g of tea to a litre of hot water, then condensed and evaporated milk to taste. Keeps two days chilled.
