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 ↓
Whiting Au Gratin
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
Preheat the oven to 350°F (175°C).
In a dish, mix butter, flour, parsley, chives, mushrooms, pepper, and salt.
Lay the cleaned whiting on top of the mixture.
Bake and serve
Cover the fish with the same seasoning and add more butter and grated bread crumbs.
Moisten with stock and let it stew slowly until it begins to stick to the dish.
Serve in the dish it was baked in.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whiting fish
- Forms the flaky main body of the dish, cooking gently in the surrounding juices.
- Butter
- Adds richness and helps the bread crumbs brown on top.
- Flour
- Thickens the cooking juices so they cling to the fish and seasoning.
- Mushrooms
- Release moisture and add savoury, earthy flavour to the mixture.
- Grated bread crumbs
- Form a crisp, golden topping through browning and drying in the oven.
- Stock
- Supplies liquid that gently stews the fish and carries flavour through the dish.
The step that matters
Moisten with stock and let it stew slowly until it begins to stick to the dish.. Gentle, slow cooking lets the stock and fish juices thicken with the flour without boiling hard. Vigorous boiling would toughen the delicate whiting and break it apart, while the sticking signals the juices are reducing.
Swap the chive
How well each one fits the dish's main ingredients (whiting, fish, butter, flour, parsley, mushroom, pepper):
- Shallotfits better
- Chivethe original
- Carrotfits about as well
- Spinachfits about as well
Fit is the average pairing score against whiting, fish, butter, flour, parsley, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
