Why it works: Thyme and parsley 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 ↓
Turbot a LA Creme
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Boil the turbot and remove all the flesh from the bones while it is still hot.
Combine 1 pint of milk, thyme, parsley, and bay leaves in a saucepan.
Simmer the mixture for 20 minutes.
Rub 2 oz of butter into 1 oz of flour.
Gradually stir the butter‑flour mixture into the sauce until it thickens.
Add the egg yolk, pepper, and salt to the sauce.
Assemble and bake
In a pudding dish, layer the sauce and fish alternately until the dish is full.
Top the last layer with bread crumbs and small pieces of butter.
Create a border of mashed potatoes around the edges of the dish.
Bake in a 400°F (200°C) oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turbot
- Provides the flaky fish flesh that forms the body of the dish.
- Flour
- Thickens the milk sauce with the butter as a roux.
- Butter
- Enriches the sauce and adds fat for flavour and browning on top.
- Milk
- Forms the liquid base of the creamy sauce.
- Egg yolk
- Enriches the sauce and adds richness and body.
- Bread crumbs
- Creates a golden, crisp topping when baked.
The step that matters
Adding the butter-flour mixture to the sauce. Stirring the roux in gradually keeps it smooth and lump-free, because flour clumps if it hits hot liquid all at once. Keep stirring while it thickens so the sauce stays even.
Swap the thyme
How well each one fits the dish's main ingredients (turbot, milk, parsley, butter, flour, egg, pepper):
- Nutmegfits better
- Capersfits about as well
- Thymethe original
- Tarragonfits about as well
Fit is the average pairing score against turbot, milk, parsley, butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
