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 ↓
Deviled Fish
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.
Prepare
Mince the fish coarsely.
In a saucepan, melt the butter, then stir in the flour and gradually add the milk to make a thick sauce.
Add the minced fish, finely mashed egg yolks, parsley, and season with salt, paprika, and lemon juice.
Bake and serve
Butter a baking dish or scallop shells and fill with the mixture.
Sprinkle bread crumbs over the top and brown in the oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk and butter into a smooth, thick sauce that holds the fish together.
- Butter
- Adds richness and flavor to the sauce and helps keep the mixture moist.
- Milk
- Forms the liquid base of the thick sauce that binds the fish and egg yolks.
- Hard-boiled egg yolks
- Add richness and body, helping the mixture set and stay creamy.
- Bread crumbs
- Form a crisp, golden browned topping when baked.
The step that matters
Make the sauce thick before adding the fish. Flour must cook into the melted butter and milk until the sauce thickens, because raw flour leaves a pasty taste and a sauce that is too thin will not bind the fish.
Swap the parsley
How well each one fits the dish's main ingredients (fish, flour, butter, milk, egg, lemon, bread):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Cinnamonfits about as well
Fit is the average pairing score against fish, flour, butter, milk, egg, lemon, bread. Candidates are from the same food group and used in at least 100 recipes.
“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.
