Vietnamese Egg Coffee

What is Vietnamese egg coffee?

This Hanoi speciality puts a pale, custard-like topping above a small serving of dark coffee. The contrast is the attraction: sweet, creamy egg foam followed by the coffee underneath. Robusta coffee is used in the Metropole Hotel’s published version, although home recipes also allow espresso.

A phin, the small Vietnamese metal drip filter, is a suitable way to prepare the base. Espresso is a practical alternative if that is the equipment you already have. Unlike the grounds-in-the-cup method explained in Turkish coffee, the coffee is brewed before the topping is added.

This recipe belongs with our coffee recipes, but the egg handling deserves particular attention before you begin.

A brief Hanoi history

The familiar origin story credits Nguyễn Văn Giảng, a bartender at Hanoi’s Metropole Hotel, now Sofitel Legend Metropole Hanoi. In the hotel’s account, reported by Michelin, scarce fresh milk prompted him to experiment with an egg-yolk topping. Treat this as an attributed origin account rather than a surviving contemporary recipe record.

The dates need a small qualification:

• 1946: Michelin dates the drink’s beginnings at the Metropole to this year.
• 1946: Café Giảng’s own website also identifies its heritage as beginning in this year.
• 1960s: Michelin’s account places Giảng’s opening of his own café in this later decade.

The sources therefore agree on the drink’s association with Hanoi and Giảng, but not on the café’s opening date. The milk-shortage explanation is supported; a precise claim that the recipe was created because of the First Indochina War is not established by these sources.

Choose the eggs safely

This method leaves the yolk raw or lightly warmed. Do not assume that pouring hot coffee underneath it makes it thoroughly cooked.

For England, Wales and Northern Ireland, current Food Standards Agency guidance permits raw or lightly cooked hen eggs carrying the British Lion mark or produced under the Laid in Britain assurance scheme for pregnant people, young children, older adults and people with certain underlying health conditions. Food Standards Scotland gives equivalent advice for these assured eggs. This is population food-safety guidance based on assessed risk, not a guarantee that an individual egg is free from Salmonella.

The assurance controls include sourcing from Salmonella-vaccinated flocks. Look for the actual assurance mark or scheme confirmation: “free-range”, “organic” or simply “British” is not the same check.

For this recipe:

• Use verified British Lion or Laid in Britain assured hen eggs, or pasteurised egg yolk labelled as suitable for uncooked preparations.
• If eggs are imported, unverified or outside those schemes, choose pasteurised yolk instead, or use a thoroughly cooked alternative.
• People who are severely immunocompromised and require a medically supervised diet should follow their clinical team’s advice. The general permission for assured raw eggs does not apply to them.

Keep eggs refrigerated until needed, reject damaged shells, wash hands and utensils after handling raw egg, and prepare the drink immediately before serving.

Vietnamese egg coffee recipe

This is a simple home adaptation of the published whipped-yolk method, not a claim to reproduce Café Giảng’s own formula. The quantities below are working recipe proportions; the preparation time is an estimate.

Recipe card

Serves: 1
Preparation and assembly: about 10 minutes, depending on brewing equipment
Allergens: egg and milk

Ingredients

• 18 g hen egg yolk, separated from an appropriately assured egg, or 18 g pasteurised yolk suitable for uncooked use
• 20 g sweetened condensed milk
• 60 ml freshly brewed, strong phin coffee or espresso
• Hot water for warming the cup and filling the serving bowl

Equipment

• Small, deep mixing bowl
• Electric hand whisk
• Kitchen scales and measuring jug
• Phin or espresso equipment
• Heatproof cup, wider heatproof bowl and teaspoon

Approximate caffeine: about 80 mg if made with 60 ml espresso, using EFSA’s illustrative espresso figure. This is not a measurement of this recipe, and actual espresso varies. It must not be applied to the phin version, whose caffeine content cannot be reliably inferred from drink volume alone. During pregnancy, the NHS advises no more than 200 mg daily from all sources; individual sensitivity also varies.

Method

1. Prepare the serving cup. Warm the heatproof cup with hot water, then empty it. Place it in the wider bowl on a stable surface.
2. Start the topping. Put the yolk and condensed milk into the small mixing bowl. Whisk for about 5 minutes, stopping to check the texture. It should become pale, thick and frothy rather than remain a loose yellow liquid. Nini Nguyen’s published recipe uses this whisking time as a guide.
3. Check the foam. Drop a small spoonful onto water in a separate glass. If it floats, the topping is ready to layer. If it immediately disperses, whisk further and check again.
4. Brew the coffee. Prepare your phin coffee or espresso using the equipment’s usual method. Measure 60 ml into the warmed cup.
5. Add the cream. Spoon the whipped mixture gently onto the coffee rather than pouring it forcefully into the centre. Aim for a distinct golden cap.
6. Serve warm. Carefully pour hot water into the outer bowl, keeping it below the cup’s rim. Serve immediately with a teaspoon. The water bath is for warmth, not egg safety.

Getting the topping and serving right

Look for thick froth, not the stiff peaks associated with an egg-white meringue. The published readiness test is useful because it checks whether the topping can sit above a liquid, rather than asking you to trust a fixed whisking time.

Keep the coffee and topping separate until you are ready to serve. The bowl of hot water maintains warmth without needing to put the assembled drink back on the hob.

These are practical troubleshooting suggestions based on the published whipping, layering and warm-serving methods, rather than results from comparative testing.

Do not confuse this warm drink with Vietnamese iced coffee. That is the useful next recipe when you want coffee and condensed milk without the egg topping.
