Why it works: Coffee and cream are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,339 recipes. Both carry 2-heptanol, which smells bitter, floral. The science ↓
Vienna Coffee
Ingredients
Directions
Make the coffee
Moisten the coffee grounds with cold water and stir in the beaten egg.
Pour half of the boiling water over the mixture and let it stand for 5 minutes at boiling point.
Add the remaining boiling water and let it stand for 5 minutes or more (not boiling).
Serve
In a separate bowl, combine the cream with the beaten egg white.
Serve by putting the cream mixture in cups and pouring the coffee over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee
- Provides the main flavour and aroma of the drink.
- Egg
- Helps clarify the brew by binding fine grounds as the egg sets.
- Cream
- Adds richness and a smooth, mellow body that softens the coffee.
The step that matters
Keep the second steep below boiling. Once the remaining water is added, the mixture should stay just under boiling. Boiling can over-extract the grounds, making the coffee harsher, and can disturb the egg that is clarifying the brew.
