Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish Pudding or Scalloped Fish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the skin and bones from the fish and break it into large flakes.
Simmer the onion and mace in the milk for 20 minutes, then strain.
Make the sauce
Melt the butter in a pan, add the flour, then gradually stir in the milk until boiling.
Cook for 2 minutes, then season well and add the fish.
Bake and serve
Pour the mixture into a buttered pie dish, cover with mashed potato, and sprinkle with browned bread crumbs.
Set in the oven at 400°F (200°C) until thoroughly hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk with the melted butter into a smooth white sauce.
- Butter
- Adds richness and carries the flour so it cooks into the sauce without lumps.
- Milk
- Forms the liquid base of the sauce that binds the fish together.
- Cold fish
- Provides the main body and flavor of the pudding.
The step that matters
Adding the milk gradually to the butter and flour. Stirring the liquid in slowly lets the starch in the flour swell evenly as it heats, so the sauce turns smooth instead of lumpy.
Swap the mace
How well each one fits the dish's main ingredients (fish, butter, flour, milk, potato, onion, pepper):
- Parsleyfits better
- Thymefits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against fish, butter, flour, milk, potato, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
