What to check first

Brewer type and filter type

This recipe shines with a strong, concentrated coffee. A traditional Vietnamese phin filter is ideal. It brews a slow drip, producing a potent shot. If you don’t have a phin, a Moka pot or even a very strong French press can work. Just aim for a bold brew.

Water quality and temperature

Good water makes good coffee. Use filtered water if your tap water has a strong taste. The ideal brewing temperature for coffee is usually between 195°F and 205°F. Too hot, and you’ll scorch the grounds. Too cool, and you won’t extract enough flavor.

Grind size and coffee freshness

For a phin filter, a medium-fine grind is usually best. It should be finer than drip coffee but coarser than espresso. Freshly roasted beans, ground just before brewing, make a huge difference. Coffee loses its aromatic compounds quickly after grinding.

Coffee-to-water ratio

This is key for that strong coffee base. For a phin filter, aim for about 15-20 grams of coffee for a 3-4 oz brew. This makes it potent enough to stand up to the rich egg topping. Experiment a bit to find what works for your taste.

Cleanliness/descale status

Make sure your coffee brewing equipment is clean. Old coffee oils can make your brew taste bitter or stale. If you use a machine, check its descaling status. A clean machine brews cleaner coffee.

Step-by-step (brew workflow)

Step 1: Prepare Your Coffee Beans

• What to do: Measure out your coffee beans. A good starting point for a single serving phin filter is about 15-20 grams.
• What “good” looks like: You have the right amount of whole beans ready for grinding.
• Common mistake and how to avoid it: Using pre-ground coffee. Grind your beans just before brewing for maximum freshness.

Step 2: Grind Your Coffee

• What to do: Grind the beans to a medium-fine consistency, suitable for a phin filter.
• What “good” looks like: The grounds have a texture like fine sand.
• Common mistake and how to avoid it: Grinding too fine (clogs the filter) or too coarse (weak coffee). Test a small amount; it should feel right.

Step 3: Prepare the Egg Yolk Mixture

• What to do: Separate 2-3 fresh egg yolks into a bowl.
• What “good” looks like: You have only the bright yellow yolks, no trace of egg white.
• Common mistake and how to avoid it: Getting shell or egg white into the yolks. Be careful when cracking eggs. A small separate bowl for each yolk can help catch mistakes.

Step 4: Whip the Egg Yolks

• What to do: Use a whisk (or a small electric mixer on low speed) to whip the egg yolks until they become thick, pale yellow, and form ribbons when lifted. This takes a few minutes.
• What “good” looks like: The mixture is airy, significantly lighter in color, and holds its shape for a moment.
• Common mistake and how to avoid it: Not whipping long enough. Undermixing results in a less frothy, less stable topping.

Step 5: Add Sweetened Condensed Milk

• What to do: Slowly drizzle in about 2-3 tablespoons of sweetened condensed milk into the whipped egg yolks while continuing to whisk.
• What “good” looks like: The mixture is smooth, creamy, and has a sweet, rich aroma.
• Common mistake and how to avoid it: Adding the condensed milk too quickly. This can deflate the whipped yolks. Drizzle it in slowly.

Step 6: Brew the Coffee

• What to do: Place the phin filter on top of your mug. Add the ground coffee and gently tamp it down. Place the press disc on top.
• What “good” looks like: The coffee grounds are evenly distributed and ready for water.
• Common mistake and how to avoid it: Tamping too hard (slows or stops the drip) or too lightly (weak coffee). Aim for gentle, even pressure.

Step 7: Bloom the Coffee

• What to do: Pour a small amount of hot water (around 195°F-205°F) over the grounds, just enough to wet them. Wait about 30 seconds.
• What “good” looks like: The coffee “blooms” and expands slightly as gases escape.
• Common mistake and how to avoid it: Skipping the bloom. This step releases CO2 and leads to a more even extraction and better flavor.

Step 8: Complete the Brew

• What to do: Fill the phin filter with hot water. Place the lid on top. Let the coffee drip slowly into the mug.
• What “good” looks like: A rich, dark stream of coffee is slowly filling your mug.
• Common mistake and how to avoid it: Rushing the process. The beauty of the phin is its slow, deliberate drip. Be patient.

Step 9: Assemble the Egg Coffee

• What to do: Once the coffee has finished dripping, gently spoon the whipped egg yolk and condensed milk mixture over the top of the hot coffee.
• What “good” looks like: A thick, creamy layer of foam sits atop the dark coffee.
• Common mistake and how to avoid it: Stirring the mixture in too vigorously. You want the distinct layers for the best experience.

Step 10: Serve and Enjoy

• What to do: Serve immediately.
• What “good” looks like: A beautiful layered drink, ready to be savored.
• Common mistake and how to avoid it: Letting it sit too long. The foam is best enjoyed fresh.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If the coffee tastes bitter, then reduce the coffee-to-water ratio or check if the water was too hot because extreme extraction can cause bitterness.
• If the egg foam is thin and watery, then whip the egg yolks longer before adding condensed milk because sufficient aeration is key.
• If the coffee drips too slowly or not at all, then the grind is likely too fine or tamped too hard because this restricts water flow.
• If the egg foam separates quickly, then it wasn’t whipped enough or the condensed milk was added too fast because these affect the emulsion.
• If the coffee tastes weak, then use more coffee grounds or a finer grind because insufficient coffee or extraction leads to a diluted flavor.
• If the egg topping tastes too sweet, then reduce the amount of sweetened condensed milk in the next batch because it’s the primary sweetener.
• If the coffee has an unpleasant sour taste, then the water temperature might be too low or the grind too coarse because under-extraction causes sourness.
• If the egg foam has a strong “eggy” smell, then the yolks might not have been fresh enough or whipped sufficiently because freshness and aeration help neutralize this.
• If you’re using a different brewer than a phin, then adjust grind size and coffee amount because different methods require different parameters.
• If the final drink is too cold, then preheat your mug or serve the coffee immediately after brewing because the egg foam is best enjoyed with hot coffee.

FAQ

What kind of coffee should I use for Vietnamese egg coffee?

You’ll want a strong, dark roast coffee. Traditional Vietnamese coffee beans are often used, but any bold, full-bodied coffee will work. A phin filter is ideal for brewing the concentrated coffee needed.

How do I get the egg foam to be thick and stable?

The key is whipping the egg yolks thoroughly until they are pale yellow and form ribbons. Then, slowly drizzle in the condensed milk while continuing to whisk. Patience during whipping is crucial.

Can I make this dairy-free?

Replacing sweetened condensed milk is tricky. Some people experiment with coconut condensed milk, but the texture and flavor will be different. The traditional recipe relies on dairy for its signature creaminess.

Is it safe to eat raw egg yolks?

Use very fresh, high-quality eggs from a reputable source. Many people enjoy egg coffee without issue. If you are concerned about raw eggs, you can gently heat the egg yolk and condensed milk mixture over a double boiler while whisking until it thickens slightly before serving.

How do I store leftover egg yolk mixture?

It’s best to make the egg yolk mixture fresh for each drink. If you have a small amount left over, store it in an airtight container in the refrigerator for no more than 24 hours, but the texture may change.

What if I don’t have a phin filter?

You can use a Moka pot for a strong brew, or even a very strong French press. The goal is a concentrated coffee base that can stand up to the rich egg topping.

Why does my egg foam taste eggy?

This usually happens if the yolks aren’t fresh enough or if they weren’t whipped long enough. Proper whipping incorporates air and helps mellow the flavor. Using very fresh eggs is important.

Can I add sugar to the coffee itself?

Traditionally, the sweetness comes solely from the egg yolk and condensed milk topping. However, you can add a little sugar to the coffee base if you prefer it sweeter, but try it the traditional way first.
