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

  1. Break off the ends of the string beans and remove the strings along the edges.

  2. Cut the beans into pieces half an inch long.

Cook and finish

  1. Boil the beans in just enough water to cover them for about one hour until tender.

  2. Once tender and most of the water has evaporated, add pepper, salt, butter, and cream.

  3. If you don't have cream, add more butter instead.

The flavor team

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.

  1. Butter + creamtop 8% of all pairs

    Shared aroma: delta-dodecalactone (sweet, creamy).

    Shared aroma: acetic acid (sour, vinegar).

Pepper and cream barely smell alike, yet cooks put them together in 21,449 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

String beans
Form the main body of the dish and soften into a tender vegetable as they cook.
Butter
Adds richness and a smooth, silky mouthfeel to the cooked beans.
Cream
Adds richness and body, giving the beans a creamier, smoother coating.

The step that matters

Simmering until most of the water has evaporated. Boiling in just enough water lets the beans cook through without becoming waterlogged. Adding the butter and cream only after most of the water is gone keeps the dairy from separating and lets it coat the beans instead of thinning in liquid.

Swap the beans

How well each one fits the dish's main ingredients (pepper, butter, cream):

  1. Almondfits better
  2. Walnutfits about as well
  3. Pistachiofits about as well
  4. 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.
