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 ↓
Green Pea Soup
Ingredients
Directions

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Break down into the body and thick texture of the soup when boiled and pressed.
- Flour
- Thickens the liquid when cooked with butter, giving the soup body.
- Butter
- Fat that combines with flour to form a roux, helping it thicken smoothly.
- Meat stock
- Adds savory depth and liquid to the soup.
The step that matters
Stir in the flour and butter until thick. Flour rubbed into butter must be stirred into the hot liquid and kept moving so it dissolves without lumps, then thickens as it heats. Adding it cold or leaving it unstirred can cause clumping.
Swap the mint
How well each one fits the dish's main ingredients (peas, parsley, sugar, pepper, flour, butter, meat):
- Thymefits better
- Tarragonfits better
- Marjoramfits better
- Mintthe original
Fit is the average pairing score against peas, parsley, sugar, pepper, flour, butter, meat. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
