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 ↓
French, String and Wax Beans
Ingredients
Directions
Prepare the beans
Snap the beans when bent, string them, break off the ends, and cut into 2 or 3 pieces.
Soak the beans in cold water for 15 minutes, then drain.
Cook
Boil salted water in a pot, add the beans, cover, and boil for 30 minutes.
Uncover and cook for an additional 30 to 60 minutes, depending on the type of beans.
Cook a piece of salt pork with the beans.
Finish and serve
If the beans are nearly dry, do not drain; add butter, sweet cream, and more salt if needed.
Remove the pork and drain the water before serving with cream or cream sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String or wax beans
- Form the main body of the dish, becoming tender as they simmer for a long time.
- Butter
- Adds richness and a silky mouthfeel to the cooked beans.
- Sweet cream
- Adds richness and body, softening the flavour and giving a creamy coating.
The step that matters
Draining only when the beans are not nearly dry. Beans cooked in very little liquid can scorch and stick, and the cooking water carries flavour. Draining is skipped when the beans are nearly dry so they keep their moisture and fat, while draining excess water when there is more liquid keeps the dish from being watery.
Swap the beans
How well each one fits the dish's main ingredients (butter, cream, pork):
- Almondfits better
- Peanutfits better
- Filbertfits about as well
- Beansthe original
Fit is the average pairing score against butter, cream, pork. Candidates are from the same food group and used in at least 100 recipes.
