Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the main body of the dish and carry the texture once cooked until tender.
- Cream
- Adds richness and a smooth, body-rich liquid that coats the beans.
- Butter
- Adds fat for richer flavor and a silkier mouthfeel in the sauce.
- Flour
- Thickens the cream as its starch swells with heat, giving the sauce body.
The step that matters
Heating the cream mixture. Flour thickens cream only as its starch swells with gentle heat and is well blended in. Cream can scorch or separate if it boils hard, so keep the heat moderate and stir while it warms.
Swap the beans
How well each one fits the dish's main ingredients (cream, butter, flour, pepper, pork):
- Almondfits better
- Chestnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against cream, butter, flour, pepper, pork. Candidates are from the same food group and used in at least 100 recipes.
