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 ↓
Salmon Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Remove skin and bones from the salmon and chop it coarsely.
In a bowl, combine the salmon, mashed potatoes, white breadcrumbs, and oiled butter.
Season with coarse sea salt and black pepper, then stir in the eggs and enough milk to form a stiff batter.
Bake and serve
Grease a baking dish and pour in the salmon mixture.
Sprinkle the top with browned breadcrumbs and add small bits of butter.
Bake in a moderate oven at 350°F (175°C) for about 1 hour, or until set.
Serve hot or reheat before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the pie and gives it its flavour.
- Eggs
- Bind the mixture and help it set firm when baked.
- Mashed potatoes
- Add body and moisture, keeping the filling soft and tender.
- White breadcrumbs
- Absorb liquid and help give the mixture a stiff, sliceable texture.
- Milk
- Loosens the mixture into a batter and adds moisture as it bakes.
- Butter
- Adds richness and fat, and browns the topping in the oven.
The step that matters
Adding the milk to form a stiff batter. Too much milk leaves the pie wet and slow to set, while too little makes it dry and crumbly. Eggs set as they heat, so the liquid balance determines the final texture.

Fit is the average pairing score against salmon, butter, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
