Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Halibut Moulds
Ingredients
Directions
Poach the fish
Boil the halibut with the bay leaf, green pepper, salt, and white pepper in a chafing dish for a few minutes.
Break the cooked fish into pieces and mix in the egg white and cracker crumbs to help it hold shape.
Grease small moulds and fill them with the fish mixture.
Optionally, add strips of green pepper or an egg in the center.
Make the cheese sauce
For the sauce, melt the butter and flour together.
Gradually stir in the milk until thickened.
Add the American cheese and paprika to the sauce, stirring until smooth.

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
- Halibut
- Forms the main body of the mould and provides the flaky texture.
- Egg white
- Binds the fish pieces together so the moulds hold their shape.
- Cracker crumbs
- Absorb moisture and help the fish mixture hold together when set.
- Butter
- Enriches the sauce and carries flavour through the roux base.
- Flour
- Thickens the milk into a smooth sauce when cooked with the butter.
- American cheese
- Melts into the sauce to add richness and a smooth, creamy body.
The step that matters
Gradually stir in the milk. Adding the milk slowly to the hot butter and flour roux lets the starch disperse evenly, so the sauce thickens smooth rather than lumpy.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, butter, flour, milk, cheese):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against egg, butter, flour, milk, cheese. Candidates are from the same food group and used in at least 100 recipes.
