Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Cream Sauce for Fish
Ingredients
Directions
Combine fish bones, cold water, parsley, salt, and peppercorns in a pot.
Simmer until reduced to just under ¼ pint, skimming frequently.
Add lemon peel or shallot for flavor.
Strain the liquid and add cream to make nearly ½ pint.
Beat in the egg yolk and remove from heat before boiling.
To reheat fish, moisten it with the sauce and place between two plates over boiling water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Swap the parsley
How well each one fits the dish's main ingredients (lemon, cream, egg):
- Nutmegfits about as well
- Tarragonfits about as well
- Parsleythe original
- Dillfits less well
Fit is the average pairing score against lemon, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
