Why it works: Thyme and pepper are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Steam the fish until cooked through, then remove the bones.
Make the sauce
In a kettle, combine milk, flour, thyme or sage, salt, pepper, and onion slices. Cook until thickened.
Stir in butter and eggs until well combined.
Assemble and bake
In a large baking dish, layer fish, seasoning with salt and pepper, then add the filling until the dish is full.
Top with bread crumbs and cheese if desired.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turbot
- Forms the flaky main body of the dish, providing the bulk of the protein.
- Milk
- Forms the liquid base of the filling, which thickens into a creamy sauce.
- Flour
- Thickens the milk into a smooth sauce as it cooks.
- Butter
- Adds richness and a silky texture to the sauce.
- Eggs
- Bind the filling and set on baking, giving it a custard-like firmness.
- Bread crumbs
- Form a crisp, golden topping through browning in the oven.
The step that matters
Cooking the sauce until thickened. Flour must be cooked long enough in the hot milk to swell and thicken fully; undercooked flour leaves a raw, pasty taste and a thin filling. Stirring keeps the mixture smooth and prevents scorching on the base of the kettle.
Swap the onion
How well each one fits the dish's main ingredients (turbot, milk, flour, thyme, pepper, butter, egg):
- Leekfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against turbot, milk, flour, thyme, pepper, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
