"Salt coffee" sounds like a gimmick the first time you hear it. One sip usually changes that: a lightly salted cream, strong coffee and sweet milk come together, the bitterness softens, and the coffee flavour actually comes through more clearly.
From Huế to everywhere
Salt coffee comes from Huế. It's generally said to have appeared in small cafés around the city in the early 2010s and caught on widely over the following years. Today you'll find it from Đà Nẵng to Hanoi and Saigon, each café with its own take: some top it with whipped cream, others with a simple mix of fresh milk, condensed milk and salt.
Why does salt make coffee less bitter?
It isn't just in your head. In taste science, salt (specifically sodium) is known to suppress how strongly we perceive bitterness. With bitterness turned down, the sweetness and aroma of the coffee step forward. It's the same reason people salt watermelon or add salt to chocolate.
The key is restraint: a small pinch is all you want. Get it right and you barely taste salt, just a rounder cup. Overdo it and the drink turns briny.
For one glass
- 20 g of ground coffee, brewed in a phin with about 60 ml of water. A Robusta-forward Phin Ground is the traditional choice.
- 1–1½ tablespoons of condensed milk for the coffee.
- Salted cream: 40 ml whipping cream, 20 ml fresh milk, 1 tablespoon condensed milk and a small pinch of salt (around 0.5 g, what you can hold between two fingertips).
- Ice.
Method
- Brew the coffee straight onto the condensed milk and stir well.
- Make the salted cream: put the cream, milk, condensed milk and salt in a chilled bowl and whisk for 1–2 minutes, until thickened but still pourable (soft peaks). It shouldn't be stiff.
- Fill a glass with ice and pour in the milky coffee.
- Float the cream on top, pouring gently over the back of a spoon so it sits as a separate layer. A few flakes of salt or a dusting of ground coffee on top is a nice finish.
- To drink: take the first sip through the cream, then stir to bring it all together.
Tip: No cream? Froth 50 ml of fresh milk with 1 tablespoon of condensed milk and the pinch of salt using a handheld milk frother. The topping is lighter, but still delicious.
Troubleshooting
| Problem | Fix |
|---|---|
| The cream sinks straight away | Whip it a little thicker, and keep the cream and bowl well chilled |
| You can clearly taste salt | Cut back to a few grains and add a touch more condensed milk to the cream |
| Too sweet and heavy | Use less condensed milk in the coffee and leave the cream as is |
