Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
A Nice Way to Dress and Bake 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 the fish
Boil the fish until done, then remove the bones and sprinkle with salt and cayenne pepper.
Make the sauce
Heat the milk in a saucepan.
In a separate bowl, cream together the butter and flour, then add to the heated milk.
Boil the mixture until thick, then let it cool.
Stir in the eggs, parsley, and onion into the cooled mixture.
Bake and serve
In a baking dish, layer the fish and sauce alternately until filled.
Cover the top with stale bread crumbs and small pieces of butter.
Bake at 350°F (175°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish or haddock
- Forms the flaky main body of the dish, becoming tender when cooked and baked.
- Flour
- Thickens the milk into a sauce when cooked with butter and heated liquid.
- Butter
- Adds richness and fat, enriching the sauce and helping the topping brown.
- Milk
- Forms the liquid base of the sauce, which thickens as it boils.
- Eggs
- Stirred into the cooled sauce to help bind and set it during baking.
The step that matters
Boil the mixture until thick, then let it cool.. The flour must be fully cooked in the boiling milk to thicken properly, since raw flour tastes pasty and thickens poorly. Cooling before adding the eggs keeps the heat from scrambling them.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, flour, butter, parsley, pepper, egg):
- Potatofits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against fish, milk, flour, butter, parsley, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
