Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Form the body of the dish, absorbing the sauce as they cook.
- Sauce tournee (no. 6)
- Provides the base sauce that carries the beans and flavour.
- Egg yolks
- Thicken the sauce as they set gently with heat.
- Cream
- Adds richness and smoothness to the thickened sauce.
The step that matters
Thicken the sauce with beaten egg yolks and cream. Egg yolks thicken when heated gently, but if the sauce boils after they are added they can scramble and turn grainy. Keep the heat low and stir steadily.
Swap the parsley
How well each one fits the dish's main ingredients (beans, sauce, onion, sugar, egg, cream):
- Capersfits better
- Nutmegfits better
- Garlicfits better
- Parsleythe original
Fit is the average pairing score against beans, sauce, onion, sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
