Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
White Soup Without Meat
Ingredients
Directions
Make the stock
In a pot, boil the onion, turnip, celery, parsley, bay leaves, and whole peppers in 1 quart of water for 8 hours until reduced to ½ pint.
Strain the mixture and season with coarse sea salt.
Finish the soup

Add the milk and let it boil again.
Pour the hot soup over the beaten egg, stirring well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the creamy body and mild sweetness of the white soup.
- Egg
- Enriches the soup and thickens it gently when heated with the hot liquid.
- Flour
- Thickens the soup with butter as a roux, giving it body.
- Butter
- Adds fat and richness, carrying flavor and helping form the roux with flour.
- Onion
- Builds the savory aromatic base of the vegetable stock.
The step that matters
Pouring the hot soup over the egg. If the soup is added too quickly or is too hot without constant stirring, the egg can scramble instead of smoothly thickening the soup. Stirring well while pouring gently tempers the egg.
