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 ↓
Pink Cream Soup
Ingredients
Directions
Make the soup
In a saucepan, melt butter and flour over heat until smooth.
Gradually add milk and bring to a boil.
Season with salt and nutmeg.
Sieve in boiled beets to color the soup pink.
Make and cook the marrow balls
In a bowl, mix marrow, bread crumbs, parsley, salt, and pepper.
Add raw egg to form a smooth paste and shape into balls the size of a filbert.
Drop balls into boiling water and cook for 15 minutes.
Serve five marrow balls in each bowl of soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the soup and adds richness and a rounded flavor to the base.
- Flour
- Melted with butter, it thickens the milk into a smooth, body-rich soup.
- Milk
- Forms the liquid base of the soup, giving it creaminess when brought to a boil.
- Raw egg
- Binds the marrow, crumbs and parsley into a smooth paste that holds its shape.
- Bread crumbs
- Add bulk to the marrow mixture, helping the balls hold together and stay tender.
- Boiled beets
- Sieved into the soup to give it a pink color.
The step that matters
Shaping and cooking the marrow balls in boiling water. The paste must be smooth and firmly bound, or the balls can break apart in the pot. Keeping the water at a steady boil helps the egg set and the balls hold their shape while cooking.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, milk, nutmeg, bread, egg, pepper):
- Cinnamonfits better
- Parsleythe original
- Marjoramfits about as well
- Cardamomfits about as well
Fit is the average pairing score against butter, flour, milk, nutmeg, bread, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
