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, then remove the bones and flake the fish.
Make the sauce
In a saucepan, combine milk, thyme, parsley, and onion. Simmer until well flavored.
Wet the flour and stir it into the butter in a separate pan. Cook until thickened.
Strain the mixture into the beaten eggs and season with pepper and salt.
Bake and serve
In a pudding dish, layer some salt, followed by a layer of fish, then pour sauce on top.
Cover with cracker crumbs and 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 fish that forms the body of the dish.
- Milk
- Forms the liquid base of the sauce, giving it a smooth, creamy texture.
- Flour
- Thickens the sauce when cooked with butter, giving it body.
- Butter
- Adds richness and flavor and helps form the flour-based thickener.
- Eggs
- Thicken the sauce when gently combined, giving it a set, custard-like texture.
The step that matters
Strain the mixture into the beaten eggs. Adding hot sauce to eggs too quickly can scramble them. Pour slowly while whisking so the eggs warm gradually and the sauce stays smooth.
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.
