Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,037 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Fish a LA Creme
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Poach the fish
Rub the fish with coarse sea salt and place it in a kettle with enough boiling water to cover it.
Once it boils, reduce the heat and let it simmer for 1 hour.
Remove the fish and carefully draw out all the bones.
Make the sauce
In a saucepan, mix 1 ounce of flour with 1 quart of cream or new milk until smooth.
Add the juice of 1 lemon, chopped onion, parsley, nutmeg, salt, and pepper.
Cook over low heat, stirring until it thickens, then stir in ¼ pound of butter.
Strain the sauce through a sieve.
Assemble and bake
Place a little sauce on a dish, lay the fish on top, and pour the remaining sauce over it.
Beat the whites of 6 eggs until frothy and spread over the fish.
Bake at 350°F (175°C) for 30 minutes or until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cream into a smooth, pourable sauce as it cooks.
- Cream or new milk
- Forms the rich base of the sauce and gives it a smooth, creamy texture.
- Butter
- Adds richness and a silky finish when stirred into the thickened sauce.
- Whites of eggs
- Whipped to a froth, they set in the oven to form a light, browned topping.
- Lemon juice
- Adds acidity that brightens the flavour of the rich cream sauce.
The step that matters
Cooking the sauce until it thickens. Flour must be cooked with the liquid over low heat and stirred constantly so it thickens smoothly without scorching or lumping. Adding butter after thickening keeps the sauce glossy.

Fit is the average pairing score against fish, flour, cream, lemon, parsley, nutmeg, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
