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 ↓

Make the soup

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green beans
- Form the main body and thick texture of the soup once puréed.
- Butter
- Adds fat and richness, giving the soup a smoother mouthfeel.
- Flour
- Thickens the liquid as it heats, helping the soup hold body.
- Vegetable broth
- Provides the liquid base that carries the puréed beans.
- Spinach
- Contributes green color to the soup.
The step that matters
Stir on the heat until it boils. Flour needs to be fully incorporated and brought to a boil to thicken properly. Stirring prevents lumps and scorching on the bottom of the pan.
Swap the green beans
