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

French beans
Form the main vegetable and provide the tender, crisp-cooked texture of the dish.
Butter
Adds fat and rich flavor to the finished beans.
Flour
Thickens the melted butter, helping it cling to the beans.

The step that matters

Boil the beans quickly, uncovered. Boiling briskly in plenty of boiling water cooks the beans fast and helps keep their chlorophyll green. Prolonged cooking lets acids released from the vegetable turn the green colour olive-brown, so drain them as soon as they are done.

Swap the beans

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

  1. Almondfits better
  2. Macadamia nutfits better
  3. Cashew nutfits better
  4. Beansthe original

Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
