Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Soup a LA Reine
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the soup
In a pot, bring the chicken stock to a simmer.
Add the cooked rice and let it cook for 5 minutes.
In a bowl, whisk together the egg yolks and heavy cream.
Slowly add a ladle of hot stock to the egg mixture, stirring constantly.
Pour the egg mixture back into the pot, stirring gently.
Season with salt and pepper, and heat through without boiling.
Serve
Serve hot, garnished with chopped parsley.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken stock
- Forms the liquid base that carries the rice and enriched custard.
- Heavy cream
- Adds richness and a smooth, velvety texture to the finished soup.
- Cooked rice
- Adds body and soft texture to the soup.
- Egg yolks
- Thicken the cream and stock mixture gently, giving a silky body when heated slowly.
The step that matters
Tempering the egg yolks. Adding hot stock to the yolks slowly, while stirring constantly, raises their temperature gradually. This keeps them from scrambling when they are returned to the pot, so the soup stays smooth.
