Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Fish Turbot
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
Boil the fish until cooked.
Remove all bones and shred the fish finely.
Make the sauce
Bring milk, onion, and parsley to a boil.
Mix flour with cold milk and egg yolks.
Stir the mixture into the boiling milk.
Season with white pepper, thyme, butter, and salt.
Assemble and bake
Butter a baking pan.
Layer sauce, fish, and finish with sauce on top.
Sprinkle with cracker crumbs and cheese.
Bake for 1 hour 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
- Haddock or whitefish
- Provides the flaked body of the dish, forming the bulk of the layers.
- All-purpose flour
- Thickens the milk sauce as its starch swells with heat, giving it body.
- Egg yolks
- Enrich the sauce and help it set creamy and rich when baked.
- Milk
- Forms the base of the sauce, supplying moisture and a mild, creamy flavor.
- Butter
- Adds richness and fat to the sauce, carrying flavor and smoothing texture.
- Cheese
- Melts and browns on top, adding savoriness and a golden crust.
The step that matters
Stir the flour mixture into the boiling milk. Flour must be fully blended before heating so it does not clump; once it meets hot milk, starch swells and thickens the sauce, and lumps are hard to fix.
Swap the white pepper
How well each one fits the dish's main ingredients (haddock, milk, onion, parsley, flour, egg, thyme):
- Marjoramfits better
- Capersfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against haddock, milk, onion, parsley, flour, egg, thyme. Candidates are from the same food group and used in at least 100 recipes.
