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
