Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Melt the butter in a saucepan.
Add the flour and mix until smooth.
Gradually add the milk, stirring until it boils.
Stir in the cream, pepper, and salt; cook for 2 minutes.
Assemble and brown
Break the fish into rough pieces and add it to the sauce, heating through.
Transfer to a flat dish, sprinkle with cheese or bread crumbs and additional pepper.
Brown in a hot oven at 400°F (200°C) until golden.

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 dish, providing the flaky texture and substance.
- Butter
- Adds richness and fat, and helps form the base of the sauce.
- Flour
- Thickens the butter and milk into a smooth, stable sauce.
- Milk
- Forms the liquid of the sauce, which thickens as it heats with the flour.
- Cream
- Adds richness and a smoother, silkier mouthfeel to the sauce.
- Cheese or bread crumbs
- Forms a topping that turns golden and crisp in the oven through browning.
The step that matters
Gradually add the milk, stirring until it boils. Adding milk slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly instead of forming lumps.
