Egg coffee sounds like a mistake, but it names two real and very different drinks, each of which combines coffee and egg for its own reason. The first is Vietnamese egg coffee, a Hanoi specialty where whipped egg yolk and sweetened condensed milk float on strong dark coffee like a warm custard. The second is Scandinavian egg coffee, a Nordic-American method where a whole egg is stirred into the grounds before boiling to produce a remarkably clear, smooth pot. This guide explains both and shows you how to make each one at home.
What is egg coffee? Two traditions that combine coffee and egg
The phrase "egg coffee" points at two unrelated drinking cultures that happen to share an ingredient. They do not taste alike, they are not made alike, and the egg plays an opposite role in each. In one, the egg is the luxurious topping. In the other, the egg never reaches your cup at all.
In Vietnamese egg coffee, the egg is a dessert-like garnish: a whipped, sweet, custard foam that you sip through or stir down into the coffee. In Scandinavian egg coffee, the egg is a clarifying agent: it binds to the grounds during boiling and is left behind, so the coffee pours out clean and smooth. Understanding that difference is the whole story, so it helps to take them one at a time.
Vietnamese egg coffee (ca phe trung)
Vietnamese egg coffee, or ca phe trung, was created in Hanoi in the 1940s. The widely told story credits Nguyen Van Giang, who reached for whipped egg yolk as a stand-in when fresh milk was scarce. He later opened Cafe Giang in the Old Quarter, where his family still serves the drink today. It tastes like a warm coffee custard or a tiramisu in a cup: rich, sweet, and barely bitter.
The base is strong, dark, often robusta-forward coffee, traditionally brewed in a small metal phin filter that drips straight into the glass. On top sits a thick, glossy foam whipped from egg yolk and sweetened condensed milk. The foam insulates the coffee and keeps it hot, which is why the drink is usually served warm in a small glass set in a bowl of hot water. For the wider picture of how this fits Vietnamese coffee culture, see our overview of what Vietnamese coffee is, and for the chilled version try iced Vietnamese coffee.
How to make Vietnamese egg coffee
You will need: strong brewed coffee, one or two egg yolks, and a couple of spoonfuls of sweetened condensed milk. A small whisk or a handheld milk frother makes the foam far easier.
- Brew the coffee strong. Use a phin filter, a moka pot, or any concentrated brew you like. Aim for a small, intense serving rather than a long mug.
- Separate the yolks. Put one or two egg yolks into a deep bowl or jug. Add one to two tablespoons of sweetened condensed milk.
- Whip until pale and thick. Beat hard for several minutes, until the mixture lightens in color, roughly triples in volume, and holds soft, airy peaks like a loose meringue.
- Pour the coffee. Add the hot coffee to a small heatproof glass or cup.
- Float the foam. Spoon the egg foam gently over the top so it sits on the surface. Dust with a little cocoa or instant coffee if you like. Sip through the foam, or stir it down for a creamier blend.
Scandinavian egg coffee
Scandinavian egg coffee is the opposite idea. Here a whole raw egg, sometimes including the crushed shell, is mixed into the dry grounds and then boiled in the pot. The egg protein binds to the coffee particles in a process called flocculation: the grounds clump together, rise, and are then dropped out of the liquid, taking bitterness and sediment with them. What is left is famously clear, mellow, and low in bitterness.
The method traveled with Scandinavian immigrants to the United States' Upper Midwest in the 1800s and became a fixture at Lutheran church gatherings, where huge pots were brewed for the congregation. That is why it is still nicknamed "church basement coffee." It is a close cousin of the boiled-grounds approach in our guide to cowboy coffee, but the egg is what makes it clean rather than gritty.
How to make Scandinavian egg coffee
You will need: ground coffee (medium-coarse works well), one egg, water, and a pot.
- Make the egg slurry. Crack one whole egg into a bowl, add a splash of cold water, and stir in your ground coffee until you have a thick, dark paste.
- Boil the water. Bring a pot of water to a rolling boil.
- Add the paste and boil briefly. Stir the egg-and-coffee mixture into the boiling water and let it boil for about three minutes. The grounds will gather into clumps and float to the top.
- Settle with cold water. Take the pot off the heat and pour in a measure of cold water. This sinks the clumps to the bottom and helps trap any stray particles.
- Pour off the clear coffee. Let it rest a minute, then gently pour or strain the smooth, clarified coffee off the top, leaving the egg-bound grounds behind.
Vietnamese vs Scandinavian egg coffee
| Feature | Vietnamese egg coffee (ca phe trung) | Scandinavian egg coffee |
|---|---|---|
| Origin | Hanoi, Vietnam, 1940s (Cafe Giang) | Nordic tradition, popular in the US Upper Midwest |
| Part of the egg used | Egg yolk only, whipped with condensed milk | A whole raw egg (sometimes with shell) |
| What the egg does | Becomes a sweet, custard-like foam topping | Clarifies the brew by binding grounds and bitterness |
| Does the egg reach the cup? | Yes, it is the topping you drink | No, it is left behind with the grounds |
| Taste | Sweet, rich, dessert-like, barely bitter | Clear, smooth, mellow, clean-finishing |
| Usually served | Warm in a small glass (also iced) | Hot, by the potful, often for a crowd |
A note on raw eggs and caffeine
The Vietnamese version uses a barely cooked, whipped yolk, so food safety matters. Use very fresh or pasteurized eggs, and keep things clean. Pregnant people, young children, older adults, and anyone who is immunocompromised may prefer to avoid drinks made with raw or lightly cooked egg, or to choose a pasteurized-egg product. The Scandinavian version boils the egg fully, which is reassuring, though the same use-fresh-eggs advice applies. This is general guidance, not medical advice.
On caffeine: both drinks are built on real coffee, so they are not caffeine-free. The amount depends entirely on how much coffee you brew and how strong it is, not on the egg. A small, intense Vietnamese serving can pack a punch despite its modest size, while a big Scandinavian pot spreads the caffeine across many cups.
Which egg coffee should you try first?
If you want a sweet treat that blurs the line between coffee and dessert, start with the Vietnamese cup. If you are curious how an egg can make a plain pot of coffee taste cleaner and rounder, the Scandinavian method is the better experiment. Either way, egg coffee is proof that the most surprising pairings often come from solving a very practical problem, a scarce ingredient in one case and gritty boiled coffee in the other.
