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 ↓
Scalloped Fish
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Boil the whitefish until cooked.
Remove the bones and flake the fish.
Make the sauce
Combine milk, thyme, parsley, and onion in a saucepan.
Simmer the mixture until well flavored.
Wet the flour.
Stir the wet flour into melted butter in a separate pan.
Cook the mixture until thickened.
Strain the thickened mixture into the beaten eggs.
Season the mixture with pepper and salt.
Assemble and bake
Layer some salt in a pudding dish.
Place the flaked fish on top of the salt layer.
Pour the sauce over the fish.
Cover the dish with cracker crumbs.
Bake in a hot oven at 400°F (200°C) until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whitefish
- Provides the flaked, tender body of the dish.
- Flour
- Thickens the butter and milk into a smooth, stable sauce.
- Butter
- Carries the flour and adds richness and a silky mouthfeel to the sauce.
- Eggs
- Enrich and set the sauce, giving it body when baked.
- Milk
- Forms the liquid base of the sauce, adding creaminess.
The step that matters
Cook the flour and butter until thickened. The flour must be fully cooked in the butter and milk mixture so it thickens smoothly and loses its raw starchy taste. Straining before adding the eggs removes lumps, and the eggs should be added to a sauce that is not boiling so they do not scramble.
Swap the thyme
The recipe marks thyme as optional. How well each one fits the dish's main ingredients (whitefish, milk, parsley, onion, flour, butter, egg):
- Capersfits about as well
- Nutmegfits about as well
- Thymethe original
- Garlicfits about as well
Fit is the average pairing score against whitefish, milk, parsley, onion, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
