Most Hong Kong milk tea recipes online have one of two problems. Either they measure the tea by volume – cups and tablespoons – which is unreliable for tea, where a few grams genuinely change the cup; or they're tangled up in a translation error that sends people looking for the wrong ingredient.
Here's the one that trips everyone up:
Hong Kong milk tea is made with black tea. The Chinese name, 紅茶 (Cantonese: hùhng chàh; Mandarin: hóngchá), translates literally as "red tea" – and a lot of recipes repeat that word. But "red tea" in English usually means rooibos, which is something else entirely. What 紅茶 actually means is what English calls black tea. So when a recipe says red tea, reach for a strong black tea – specifically a Ceylon-based blend.
I grew up in Hong Kong, and the version below is the one I make at home. There's no single "correct" recipe – every cha chaan teng guards its own blend. This is mine. It works, and it reminds me of home. It's in grams and millilitres for the tea (where it matters), with US measures in brackets, and spoons for the milk. It's also far simpler than the long recipes make it look – boil, strain, mix.
- 1,200 ml (5 cups) water
- 15 g (0.5 oz) Ceylon black tea
- 10 g (0.35 oz) Assam
- 4 g (0.15 oz) bo lei (普洱, Pu'er)
- 2 tsp condensed milk (sweetness)
- 50 ml (1¾ fl oz) evaporated milk (body; up to 75 ml / 2½ fl oz if you like it milkier)
- No separate sugar – the condensed milk does that job.
- Boil the water. Bring all 1,200 ml (5 cups) to a boil.
- Add the tea and boil for 7 minutes. A full rolling boil – not a gentle steep. It'll taste harsh on its own; that's correct.
- Rest 2 minutes. Turn off the heat; it settles and keeps extracting off the boil.
- Strain through a cloth sock. A single strain is fine; pull it back and forth a few times if you want it smoother.
- Assemble each mug. Fill ~halfway with tea (150 ml), add 50 ml evaporated (up to 75 ml for milkier) and 2 tsp condensed milk, stir. Leave a little headroom.
What you'll need (the detail)
Why three teas? Ceylon gives the bright backbone, Assam adds body and malt, and a little bo lei rounds it out with an earthy depth. Most recipes reach for English Breakfast tea bags – that's not what gives it the cha chaan teng character. Most also skip the bo lei, which is a small thing that makes it taste properly Hong Kong rather than just "strong black tea." (Cha chaan tengs typically use finely broken "tea dust" for a fast, hard extraction; loose leaf works just as well at home, with a cleaner pour.) And here's the thing most recipes get wrong: measure your tea by weight, not volume. A tablespoon of fluffy whole leaf and a tablespoon of dense fannings can differ in weight by half – which is exactly why so many homemade cups come out randomly strong or weak. Grams fix that.
A note on cheap bo lei (普洱). If you're using a very low-grade bo lei, give it a quick rinse first: pour boiling water over just the bo lei, swirl for a few seconds, and tip that water out before you brew. It washes off the musty note that cheap Pu'er can have. Good bo lei doesn't need this – skip it if yours smells clean.
Per mug (a mug holds roughly 150 ml of tea):
- 2 teaspoons condensed milk (sweetness) – a little more if you're serving it over ice
- about 50–75 ml (1¾–2½ fl oz) evaporated milk (body) – start at the lower end and add more to taste
- No separate sugar – the condensed milk does that job.
A note on the milk. This is the part recipes muddle most. The two milks do different jobs: evaporated milk gives the creamy body, condensed milk gives the sweetness. You don't need both and sugar – the condensed milk is the sugar. In Hong Kong the default is Black & White (黑白淡奶), the Dutch evaporated milk brand the cafés swear by. It's not richer than other evaporated milk – it's just the cha chaan teng standard, prized for its mouthfeel and faint caramel note.
And a warning: don't reach for the fresh milk in your fridge door. Some recipes suggest regular milk, and I've tried it – even full-cream is too thin and watery to stand up to a brew this strong, and the result tastes weak and washed out. Evaporated milk is concentrated and richer, which is the whole point: it has the body to match the tea.
Equipment: A cloth "sock" strainer – the fine-mesh cloth bag used for tea across Asia, from Hong Kong to Bangkok. It's a few dollars at any Asian supermarket. (This is the "silk stocking" the tea is named after.)
Method
- Boil the water. Bring all 1,200 ml (5 cups) to a boil.
- Add the tea and boil for 7 minutes. Yes, a full rolling boil – this isn't gentle steeping. It pulls out a lot of tannin, and the tea will taste harsh and bitter on its own. That's correct. The bitterness is the point; the milk balances it. If you've made HK milk tea before and it came out "too bitter," you weren't doing it wrong – you just hadn't added enough milk.
- Turn off the heat and let it rest for 2 minutes. It keeps extracting gently off the boil and settles before straining.
- Strain through the cloth sock. A single strain works perfectly – it's what I do at home. If you want to go further, you can "pull" it: pour the tea back and forth between the sock and a pot several times. This aerates it and smooths the tannin. It's not necessary, but it does make it better.
- Assemble each mug. Fill the mug about halfway with the hot tea (roughly 150 ml), then add about 50–75 ml (1¾–2½ fl oz) evaporated milk and 2 teaspoons condensed milk, and stir. The milk makes up the rest of the mug – you'll have a little headroom at the top, not a brimful cup. Adjust to taste: start with the lower amount of milk, then add more until it's the colour you like. (I make this by eye, so treat the numbers as a reliable starting point rather than gospel.)
Diabetic or sugar-free version. Skip the condensed milk and sweeten with 1–2 sachets of Equal (or your sweetener of choice) per glass. Because condensed milk also adds a little body, add a touch more evaporated milk to keep it creamy.
Why your homemade Hong Kong milk tea tastes wrong
If you've tried this before and it didn't taste right, it's almost always one of these:
- You used fresh milk. The most common mistake. Fresh milk – even full-cream – is too thin for a brew this strong. Use evaporated milk for body and condensed milk for sweetness.
- You didn't use enough tea. This is a strong brew by design. A couple of teabags in a mug will never get there.
- You brewed it too gently. It needs a hard boil, not a delicate steep. The tannin you pull out is what the milk balances against.
- You thought the bitterness meant you'd failed. The unmilked tea should taste harsh. That's correct. Fix balance with more milk, not weaker tea.
- You went looking for "red tea." It's black tea – see the FAQ below.
A little background
Hong Kong milk tea is the everyday drink of the cha chaan teng – the fast, cheap "tea restaurants" that have fed Hong Kong since the 1950s, serving Western-influenced comfort food at local speed. The tea is the backbone of the place: strong, smooth and a little bracing, built to be drunk all day and to cut through a plate of macaroni or a pineapple bun. It runs on two things – serious caffeine and condensed milk. Its nickname, "silk stocking tea" (絲襪奶茶), comes from the fine cloth sock it's strained through, which over a day of use stains the colour of a stocking.
Cold and iced Hong Kong milk tea
Cold (straight from the fridge) is how I most often drink it in summer – and it's where the make-ahead concentrate really earns its keep. The proportions are exactly the same as the hot cup, per glass:
- about 150 ml of the cold tea concentrate
- 50–75 ml evaporated milk
- 2 teaspoons condensed milk
Pour the milk over the cold concentrate, stir, and drink it as is – no ice needed. Because the concentrate is already cold and strong from its night in the fridge, it doesn't get watered down, so the balance stays identical to the hot version. This is genuinely my everyday summer cup.
Over ice, one thing changes: use 2–3 teaspoons of condensed milk instead of two. As the ice melts it waters the glass down, and cold blunts sweetness, so it needs a touch more to hold its balance. Everything else stays the same – 150 ml tea, 50–75 ml evaporated milk – poured over a tall glass of ice.
Make it ahead – and it actually improves
Here's a trick the recipes don't tell you: the brewed tea keeps, and gets better. I make the full batch, serve some fresh on the day, then strain the rest and keep it in the fridge. The next day the flavour has deepened – and it's perfect for the cold version above.
Storage: the strained, unmilked concentrate keeps in the fridge for about two days, and the flavour deepens overnight. Mix with milk fresh each time rather than storing it pre-mixed.
One warning: this is strong stuff. A mug made from a brew this concentrated carries roughly the caffeine of two to three cups of ordinary tea. It will keep you up – which is rather the point in a cha chaan teng, but worth knowing before a second mug at dinner.

FAQ
Hong Kong milk tea recipes call for "red tea" – what is that?
It's just black tea. The confusion is a translation artefact. The Chinese name is 紅茶 (Cantonese: hùhng chàh; Mandarin: hóngchá), which literally means "red tea" – named for the reddish colour of the brewed liquid, not the leaf. In English, though, 紅茶 is simply black tea. Confusingly, "red tea" in English usually means rooibos, which is unrelated and not used here. So when a recipe says "red tea," reach for a strong black tea – a Ceylon-based blend.
What makes Hong Kong milk tea taste different?
Three things: a strong blend of black teas (here Ceylon, Assam and a little bo lei / Pu'er) brewed hard and boiled rather than gently steeped; evaporated milk for a rich body that thin fresh milk can't match; and condensed milk for sweetness. The strength and the evaporated milk are what give it the distinctive cha chaan teng character.
How do you make Hong Kong-style milk tea at home?
Boil 1,200 ml water with 15 g Ceylon, 10 g Assam and 4 g bo lei (普洱, Pu'er) for 7 minutes, rest 2 minutes, then strain through a cloth sock. Per mug, fill about halfway with the tea, add roughly 50–75 ml evaporated milk for body and 2 teaspoons condensed milk for sweetness (a little more if serving over ice). No separate sugar.
What tea is used in Hong Kong milk tea?
A strong black tea, usually a Ceylon-based blend. This recipe uses Ceylon, Assam and a little bo lei (普洱, Pu'er). Most blog recipes reach for English Breakfast tea bags, which won't give the same depth.
Can I use tea bags for Hong Kong milk tea?
You can, but it's the compromise version. Tea bags hold a small amount of lower-grade tea, so you'll need a lot of them and it still won't have the depth of the loose blend. If tea bags are all you have, use strong black tea bags (Ceylon or English Breakfast), at least one per 150 ml, and boil hard. Loose Ceylon-Assam is what makes it taste like the real thing.
Why do some Hong Kong milk tea recipes ask for "tea dust" or "orange pekoe"?
Both are just grades of black tea, not different teas. "Tea dust" (or "fannings") means finely broken tea – small particles that brew fast and strong, which is exactly why Hong Kong cafés use it. "Orange pekoe" is a whole-leaf grade; despite the name it has nothing to do with oranges or flavour (it most likely refers to the Dutch House of Orange from the early tea trade). Either works at home. Café-style dust just extracts harder and faster; a quality loose-leaf black tea like the Ceylon-Assam blend here gives you the same result with a cleaner pour.
Why does my Pu'er or milk tea smell musty?
Cheap, low-grade bo lei (普洱, Pu'er) can carry a musty note. The fix is a quick rinse: pour boiling water over just the bo lei, swirl for a few seconds, and tip that water out before you brew. It washes off the musty note that cheap Pu'er can have. Good bo lei doesn't need this – skip it if yours smells clean.
How much milk do you put in Hong Kong milk tea?
Per mug of roughly 150 ml tea: about 50–75 ml evaporated milk for body and 2 teaspoons condensed milk for sweetness. Cold from the fridge it's the same proportions; over ice, bump the condensed milk to 2–3 teaspoons to make up for the melting ice. Recipes vary a lot here, so treat it as a starting point and adjust. The key is evaporated milk for body, condensed for sweetness.
Should I use sugar or condensed milk in Hong Kong milk tea?
Condensed milk is the traditional choice and does two jobs at once – it sweetens and adds a little body. Some recipes use plain sugar instead, which works and lets you control sweetness precisely, but it's the more Western shortcut. For an authentic cha chaan teng cup, use condensed milk for sweetness and evaporated milk for body.
Why is my Hong Kong milk tea weak or watery?
Almost always because you didn't use enough tea or didn't brew it hard enough. This is a strong, concentrated brew – boiled hard, not gently steeped – and it needs to stand up to rich evaporated milk. If it tastes thin, use more tea and boil it harder, and make sure you're using evaporated milk (not fresh milk, which is too watery).
Is Hong Kong milk tea the same as yuanyang?
No. Yuanyang (鴛鴦) is a Hong Kong drink made by mixing milk tea with coffee. Hong Kong milk tea is just the tea-and-milk base on its own. Yuanyang uses this milk tea as one of its two halves.
Where did Hong Kong milk tea come from?
It's a legacy of British colonial rule. Hongkongers wanted the milky tea the British drank, but fresh milk was a scarce luxury – so they used canned evaporated milk instead, and brewed the tea far stronger to suit local taste. That's how the cha chaan teng version was born in the 1940s and 50s.
Is Hong Kong milk tea the same as Thai milk tea?
No. Both use strong black tea (often Assam) and sweetened condensed milk, but Thai milk tea – the familiar bright-orange version, usually Cha Tra Mue – is sweeter, has an added flavouring, and gets its colour from food colouring (FD&C Yellow No. 6). Hong Kong milk tea has no flavouring or colouring: it's just tea and milk, stronger and brown.
Is Hong Kong milk tea the same as Malaysian or Singaporean teh tarik?
They're close cousins. Teh tarik ("pulled tea") uses strong black tea with sweetened condensed milk, and the dramatic pouring back and forth – the "pull" – is the same technique that gives Hong Kong's "silk stocking tea" its smoothness. The main difference is that teh tarik is typically sweeter and frothier from all the pulling, while Hong Kong milk tea is stronger and less sweet. Same family, different dialect.
Why is my Hong Kong milk tea bitter?
Because it's meant to be brewed strong and boiled hard – the tea is bitter on its own by design. The milk balances it. If it's too bitter, add more condensed and evaporated milk rather than weakening the tea.
What milk is used in Hong Kong milk tea?
Evaporated milk for body and condensed milk for sweetness – traditionally Black & White (黑白淡奶), the Dutch evaporated milk brand Hong Kong cafés swear by. No separate sugar.
Can I use regular milk instead of evaporated milk?
No – or rather, you can, but it won't taste right. Even full-cream fresh milk is too thin to balance such a strong brew, and the result is weak and watery. Evaporated milk is concentrated and richer, which is exactly what Hong Kong milk tea needs. This is the single most common reason a homemade version tastes "off."
Can I make Hong Kong milk tea without sugar?
Yes. Skip the condensed milk and sweeten with a sweetener like Equal (1–2 sachets per glass), then add a little extra evaporated milk to keep the body. This makes a diabetic-friendly version without weakening the tea.
What do you strain Hong Kong milk tea with?
A cloth "sock" strainer – a fine cloth bag, the same kind used across Asia, from Hong Kong to Singapore to Bangkok. It's what gives "silk stocking tea" its name.
Can you make Hong Kong milk tea ahead of time?
Yes. Brew the concentrate, strain it, and keep it in the fridge for a day or two. The flavour deepens, and it's excellent for the cold version.
