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
Cook the sliced potatoes until nearly done.
Line a deep dish with baking powder pie crust.
Layer and bake
Layer the potatoes in the dish and season with salt, pepper, and butter.
Add a layer of oysters, then repeat the layers until the dish is filled.
Sprinkle a little flour on top and pour in the boiled milk.
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 flavour as the pie bakes.
- Oysters
- Provide the main flavour and a tender, savoury texture within the layers.
- Flour
- Thickens the milk so the filling sets into a creamy sauce rather than running thin.
- Milk
- Forms the creamy liquid that gives the filling its richness and body.
- Butter
- Adds fat and richness to the potato layers, aiding browning and flavour.
The step that matters
Pour in the boiled milk after flouring. Flour dispersed over the layers and then hydrated by hot milk thickens into a sauce. Milk that is not hot, or flour that clumps, can leave a thin or lumpy filling.
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.
