Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumber
- Provides the main fresh, delicate flavour and bulk of the soup.
- Egg
- Thickens the soup when gently whisked in, giving it a smooth, body-rich texture.
- Cream
- Adds richness and smoothness, mellowing the soup's flavour and texture.
- Butter
- Fat used to soften the onion and cucumber, carrying flavour into the soup.
- White stock
- Forms the liquid base of the soup, carrying the other flavours.
The step that matters
Gradually whisk in the beaten egg mixture. Adding the egg and cream to very hot soup too quickly can scramble the egg. Whisking slowly while the soup is hot but not boiling lets the egg thicken it smoothly.
