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, cooked until tender.
Egg yolks
Thicken the sauce as they heat, giving it a smooth, rich body.
Butter
Adds richness and a glossy texture to the sauce and beans.
Lemon juice
Adds acidity that brightens the buttery sauce.
Sauce tournee
Provides the base sauce that the egg yolks and butter thicken and enrich.

The step that matters

Thicken the sauce with the egg yolks. Egg yolks set when heated, but if the sauce gets too hot or is stirred too little, the yolks can scramble and turn grainy. Stir constantly over gentle heat until the sauce just thickens.

Swap the beans

How well each one fits the dish's main ingredients (sauce, egg, parsley, 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 sauce, egg, parsley, butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
