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 ↓
White Soup
Ingredients
Directions
Make the stock
Cover the chicken bones, minced veal, parsley, and onion with cold water and simmer for three hours until reduced to two quarts.
Strain the liquid and return it to the pot; season with salt and pepper.
Finish the soup
Boil gently and skim for ten minutes before adding the milk and boiled farina.
Simmer for another ten minutes; take out a cupful and mix it with the beaten egg.
Return the egg mixture to the soup, cover, and let it sit off the heat for two minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the soup gently and adds richness when mixed in at the end.
- Farina
- Starch that thickens the soup and gives it a smooth, body-rich texture.
- Milk
- Adds creaminess and mild sweetness, lightening the color of the broth.
- Chicken bones
- Release gelatin and flavor into the water, forming the body of the stock.
- Veal
- Adds savory meaty flavor and gelatin to the stock.
The step that matters
Adding the egg mixture. Egg thickens when heated, but if the soup is too hot or boils after the egg goes in, it can curdle and turn grainy. Tempering the egg with hot soup first and then letting it sit off the heat keeps it smooth.
