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 ↓
Oyster Pie
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.
Prepare
Slice and cook the potatoes until nearly done.
Line a deep dish with the baking powder pie crust.
Assemble
Layer the potatoes, seasoning with pepper, coarse sea salt, and butter.
Add a layer of oysters, then repeat until the dish is filled.
Sprinkle a little flour on top and pour in the boiled milk.
Bake
Cover with an upper crust and bake at 400°F (200°C) for 30 minutes.

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
- Potatoes
- Form the bulk of the filling and absorb moisture and butter as they soften.
- Oysters
- Provide the main flavour and a tender, briny texture within the layers.
- Butter
- Adds richness and fat that carries seasoning and browns the crust.
- Flour
- Sprinkled over the layers, it thickens the milk into a binding sauce.
- Milk
- Forms the creamy liquid that sets into a custard-like sauce as the pie bakes.
The step that matters
Pour in the boiled milk over the flour. Milk that is hot when added helps the flour thicken the liquid evenly, so the filling sets rather than turning watery or lumpy during baking.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, oyster, flour, milk):
- Potatothe original
- Shallotfits about as well
- Capsicumfits about as well
- Asparagusfits less well
Fit is the average pairing score against pepper, butter, oyster, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
