Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Pie
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.
Make the sauce
Drop the onion into the cold milk and bring to a boil.
Remove the onion, then add corn starch mixed with a little cold milk, butter, and seasoning.
Assemble and bake
In a baking dish, layer sauce, then fish, and repeat until all ingredients are used.
Cover the top with bread crumbs.
Bake for 30 minutes or more at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled fish
- Forms the main body of the pie, providing the flaky filling layers.
- Milk
- Forms the liquid base of the sauce that keeps the pie moist.
- Corn starch or flour
- Thickens the milk into a sauce that holds the layers together.
- Butter
- Adds richness and flavor to the sauce.
- Bread crumbs
- Forms a crisp, golden browned topping over the pie.
The step that matters
Adding the starch to the sauce. Starch must be mixed with cold milk first so it disperses without lumps, then it thickens as the sauce heats. Adding it dry or to hot liquid can cause lumps and a thin sauce.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, butter, corn, celery, pepper, bread):

- Onionthe original
Fit is the average pairing score against fish, milk, butter, corn, celery, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
