Why it works: Pepper and parsley 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 ↓
Escalloped 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
Steam the whitefish until tender, then remove the bones and sprinkle with pepper and salt.
Make the sauce
Heat the milk in a saucepan and thicken it with the flour mixed with cold milk.
Once cool, add the eggs and butter to the thickened milk mixture.
Assemble and bake
In a baking dish, layer the fish and sauce until full.
Season with onions, parsley, and thyme, then cover the top with grated bread crumbs.
Bake at 350°F (175°C) for 30 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whitefish
- Forms the main body of the dish, providing flaky texture once steamed and boned.
- Flour
- Thickens the milk into a smooth sauce that holds the fish together.
- Milk
- Forms the liquid base of the sauce, giving it a creamy, moist texture.
- Eggs
- Set when baked, helping bind the sauce and give the dish structure.
- Butter
- Adds fat and richness to the sauce, improving flavor and mouthfeel.
- Bread crumbs
- Form a crisp topping that browns in the oven.
The step that matters
Adding the eggs to the sauce. If the thickened milk is still hot when the eggs go in, they can scramble instead of blending smoothly. Letting it cool first keeps the sauce silky and lets the eggs set gently during baking.
Swap the onion
How well each one fits the dish's main ingredients (whitefish, pepper, milk, flour, egg, butter, parsley):
- Chivefits better
- Potatofits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against whitefish, pepper, milk, flour, egg, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
