Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream Sauce for Fish

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce, which thickens when heated with starch.
- Cornstarch
- Thickens the hot milk into a smooth, lightly bodied sauce.
- Butter
- Adds fat for richness and a smooth, glossy mouthfeel.
- Egg
- Enriches the sauce and adds body when gently heated into it.
The step that matters
Return the mixture to the heat and stir for one minute. The egg must be warmed gradually so it thickens without scrambling. Heating too fast or without constant stirring can curdle the egg into lumps, so keep the heat gentle and keep stirring.
Swap the parsley
How well each one fits the dish's main ingredients (milk, butter, pepper, egg):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against milk, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
