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):
- Chickpeafits better
- Walnutfits about as well
- Pistachiofits about as well
- 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.
