Directions

Prepare

  1. String the French beans and cut them into four or eight pieces.

  2. Soak them in saltwater.

Cook

  1. When the water boils, add the beans and some salt.

  2. Serve immediately to preserve their green color.

  3. Alternatively, when half-cooked, drain the water and add 2 tablespoons of strained broth.

  4. Finish with a little cream, butter, and flour.

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.

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 body of the dish and carry its green color and texture.
Broth
Adds moisture and savory flavor when the beans finish cooking.
Cream
Adds richness and a smooth, silky body to the finished beans.
Butter
Adds fat for richness and a glossy finish.
Flour
Helps thicken the cream and butter into a light coating.

The step that matters

Serve immediately after cooking. Green chlorophyll breaks down with prolonged heat and time, turning beans dull olive. Cooking briefly and serving right away keeps the bright green color.

Swap the beans

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

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

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