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):
- Walnutfits better
- Almondfits better
- Pistachiofits better
- Beansthe original
Fit is the average pairing score against egg, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
