French Mode of Cooking French Beans

Ingredients

Directions

Cook the beans

  1. Cut and boil the beans until tender.

  2. Drain the beans and place them in a stewpan over heat to dry.

Dress and serve

  1. Add the butter, pepper, salt, and lemon juice, shaking the pan to mix without breaking the beans.

  2. Once the butter is melted and everything is hot, serve immediately.

  3. For added flavor, mix in chopped parsley and lemon juice just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

French beans
Provide the main body of the dish and a tender, crisp-cooked texture.
Butter
Adds richness and a glossy coating that carries the flavor across the beans.
Lemon juice
Adds acidity that brightens the buttery flavor and balances its richness.

The step that matters

Shaking the pan to mix the butter in. Tossing gently coats the beans evenly without breaking them; stirring hard with a spoon can split the tender beans and leave butter pooled at the bottom of the pan.

Swap the beans

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

  1. Chickpeafits better
  2. Walnutfits about as well
  3. Pistachiofits about as well
  4. Beansthe original

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