Why it works: Butter and cream 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 ↓
String Beans
Ingredients
Directions
Prepare
Break off the ends of the string beans, removing the string along the edge.
Cut the beans into pieces half an inch long.
Cook and season
Boil the beans in just enough water to cover them for about one hour, until tender.
Once tender and most of the water has evaporated, add salt, pepper, butter, and cream.
If preferred, drain the beans before adding the seasoning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the body of the dish, becoming tender as they simmer in the water.
- Cream
- Adds richness and a smooth, silky texture to the cooked beans.
- Butter
- Adds fat and flavour, giving the beans a rich, glossy finish.
The step that matters
Boiling until tender with just enough water. Using only enough water to cover the beans lets them cook down so most liquid evaporates before seasoning. Too much water dilutes the flavour and can leave the beans watery, while cooking them fully softens the fibres so they become tender.
Swap the beans
How well each one fits the dish's main ingredients (pepper, butter, cream):
- Almondfits better
- Walnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against pepper, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
