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

What each ingredient does

Egg yolks
Thicken the liquor into a smooth, creamy sauce as they set gently with heat.
Butter
Adds richness and a silky texture, emulsifying into the sauce when added gradually.
Parsley
Adds fresh, herbal aroma and a bit of green flavour to the sauce.

The step that matters

Add the yolks without boiling the sauce. Egg yolks begin to scramble and curdle at higher temperatures, so the sauce must stay below boiling to remain smooth and thickened.

Swap the beans

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

  1. Walnutfits better
  2. Almondfits better
  3. Pistachiofits better
