Why it works: Fish and lemon are a kitchen classic. They rank in the top 15% of all ingredient pairs, and 1,889 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
Fish a LA Creme
Ingredients
Directions
Poach the fish
Rub the fish with coarse sea salt.
Place the fish in a kettle and cover it with boiling water.
Once it boils, reduce the heat and let it simmer for 1 hour.
Remove the fish and carefully take out all the bones.
Make the cream sauce
In a saucepan, add 1 ounce of flour and gradually mix in 1 quart of cream or whole milk until smooth.
Stir in the juice of 1 lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm saltwater fish
- Forms the main body of the dish, flaking into pieces when cooked through.
- Flour
- Thickens the cream so the sauce becomes smooth and coats the fish.
- Cream or whole milk
- Provides richness and body, forming the base of the sauce.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the cream.
The step that matters
Simmer the fish gently. Once the water boils, the heat should be reduced so the fish cooks gently. A hard boil can break the flesh apart and make it tough, which is why the fish is simmered rather than boiled.
Flavor stand-ins for the lemon

- Vanillaabout as good a flavor fit
Fit is the average pairing score against fish, flour, cream. 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.
