Why it works: Rice and pepper are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 8,379 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Rice Soup
Ingredients
Directions
Make the soup
Rub the rice through a wire sieve into the boiling stock.
Simmer for 2 minutes, then remove from heat.
Finish and serve
Beat the egg yolk and cream together.
Pour the egg and cream mixture into the stock, stirring continuously to prevent curdling.
Heat to boiling point, add pepper if desired, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled rice
- Thickens the stock and gives the soup a smooth, body-rich texture when sieved.
- Egg yolk
- Enriches the soup and thickens it gently as it heats.
- Sweet cream
- Adds richness and a softer, silkier mouthfeel to the soup.
The step that matters
Adding the egg and cream mixture to the stock. Egg yolk sets when it gets too hot, so it can curdle and turn grainy if poured in carelessly or left to boil hard. Stirring constantly while pouring spreads the heat evenly and keeps the mixture smooth.
