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 ↓
String Beans, German Style
Ingredients
Directions
Melt butter in a saucepan, add sliced onion, and sauté lightly.
Add the green beans, season with salt, pepper, and sugar, then add parsley and white broth.
Cover the saucepan and let simmer for 15 minutes.
Sprinkle flour over the beans, toss well, and cook for an additional 15 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Green beans
- Form the main body of the dish and cook down to a tender texture during simmering.
- Butter
- Adds fat and richness while softening the onion at the start.
- Onion
- Sweetens and flavors the dish as it softens in the butter.
- Flour
- Thickens the cooking liquid into a light sauce that coats the beans.
- White broth
- Provides the cooking liquid that steams the beans and carries flavor.
The step that matters
Sprinkle flour over the beans, toss well. Flour must be evenly distributed over the beans before the final cook, or it clumps and forms lumps instead of thickening the liquid smoothly.
Swap the green beans
How well each one fits the dish's main ingredients (butter, onion, pepper, sugar, parsley, flour):
- Shallotfits better
- Chivefits better
- Okrafits better
- Green beansthe original
Fit is the average pairing score against butter, onion, pepper, sugar, parsley, flour. Candidates are from the same food group and used in at least 100 recipes.
