Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the sauce
Flake the fish.
In a saucepan, melt the butter and stir in the flour to make a roux.
Gradually add the milk, stirring until thickened.
Remove from heat and let cool, then mix in the beaten eggs, parsley, and lemon juice.
Assemble and bake
In a baking dish, layer the flaked fish and sauce alternately.
Top with buttered crumbs and bake at 350°F (175°C) until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux, adding richness and flavor to the sauce.
- Flour
- Thickens the butter and milk into a smooth sauce as a roux.
- Milk
- Forms the liquid base that thickens into the sauce.
- Beaten eggs
- Add body and help set the sauce once baked.
The step that matters
Adding the eggs to the cooled sauce. Eggs scrambled in a hot sauce curdle, so the sauce should be removed from heat and cooled before the beaten eggs are mixed in. Gentle mixing keeps the sauce smooth and lets the eggs set evenly during baking.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, milk, egg, lemon):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against butter, flour, milk, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
