Why it works: Parsley and pepper 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Breaks down into pulp when boiled, giving the soup its body and thickness.
- Flour
- Starch that thickens the soup when stirred in and heated.
- Eggs
- Thicken the soup gently and add richness when stirred in off the heat.
- Heavy cream
- Adds fat and richness, giving the finished soup a smooth, velvety texture.
- Swiss cheese
- Adds savory, nutty flavor and melts into the soup for a creamy finish.
The step that matters
Adding the egg and cream mixture. Eggs can curdle or scramble if they meet hot liquid too quickly. Removing the kettle from the heat and stirring the mixture in slowly lets the eggs thicken the soup smoothly.

- Turmericfits better
- Nutmegfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against rice, onion, parsley, flour, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
