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 ↓

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.
Make the sauce
In a saucepan, combine milk, flour, parsley, thyme, and onion.
Cook over medium heat, stirring until thickened.
Cook for 10 minutes.
Remove from heat and stir in eggs and butter.
Strain the sauce.
Assemble and bake
In a baking dish, layer fish and sauce until full.
Top with breadcrumbs and grated cheese.
Bake in a preheated oven 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
- Milk
- Forms the liquid base of the sauce that coats the fish.
- Flour
- Thickens the milk into a smooth sauce as it cooks.
- Eggs
- Enrich the sauce and help it set as it cooks.
- Butter
- Adds fat and richness to the sauce.
- Fish
- Forms the main body of the dish, layered with the sauce.
The step that matters
Cook the sauce until thickened. Flour needs to be heated while stirring so it swells and thickens the milk. Stirring prevents lumps and scorching on the bottom of the pan.
Swap the onion
How well each one fits the dish's main ingredients (milk, flour, parsley, thyme, egg, butter, fish):
- Shallotfits better
- Leekfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against milk, flour, parsley, thyme, egg, butter, fish. Candidates are from the same food group and used in at least 100 recipes.
