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 ↓
Fricassee of Fish
Ingredients
Directions
Prepare the fish and milk
In a saucepan, combine the milk, onion, mace, cayenne, and lemon peel; bring to a boil.
Skin and bone the fish, then cut it into 1.5‑inch pieces.
Once the milk boils, carefully add the fish and simmer for 10‑15 minutes until cooked.
Remove the fish and keep it warm in a covered bowl over a pot of boiling water.
Make the sauce
In another saucepan, melt the butter, then add the flour and cook without browning.
Strain the milk into the butter and flour mixture, stirring well.
Boil the sauce for 2‑3 minutes, then add salt to taste.
Remove the sauce from heat, add lemon juice, and pour it over the fish.
Plate and garnish
Arrange the fish in the center of a hot serving dish.
Slice the hard‑boiled eggs into eight pieces lengthwise and place two on top of the fish, with parsley in between.
Use the remaining egg pieces to form a border around the dish, placing parsley between each piece.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish, cooked gently in the seasoned milk.
- Butter
- Melted with flour to form the base of the sauce and carries flavour.
- Flour
- Thickens the milk into a smooth sauce when cooked with the butter.
- Milk
- Poaches the fish and becomes the liquid that is thickened into the sauce.
- Hard-boiled eggs
- Provide a garnish and a rich, firm contrast to the delicate fish.
The step that matters
Boil the sauce for 2‑3 minutes after straining the milk. Flour only thickens fully when it is heated in the liquid long enough for its starch to swell; a short boil leaves the sauce thin and tasting of raw flour.
Swap the mace
How well each one fits the dish's main ingredients (fish, onion, butter, flour, parsley, pepper, lemon):
- Thymefits better
- Capersfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against fish, onion, butter, flour, parsley, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
