Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Potato Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Boil and mash the potatoes with butter and cream.
In a bowl, combine the mashed potatoes, butcher's meat, ham or bacon, hard boiled eggs, salt, and pepper.
Spread a layer of uncooked potato slices in a pie dish.
Add a layer of the meat mixture, then another layer of potato slices.
Dot with butter and season with onion, ketchup, or pickles.
Bake and serve
Pour the beaten eggs over the top and cover with the upper crust.
Bake at 350°F (175°C) for 1 hour.

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, adding starch and a soft, moist body.
- Butter
- Adds richness and fat, carrying flavour and helping the potatoes taste smooth.
- Cream
- Adds moisture and richness, keeping the mashed potato soft and spreadable.
- Eggs
- Beaten eggs poured over the top set during baking, binding the layers together.
- Butcher's meat
- Supplies the savoury main filling and its meaty flavour.
The step that matters
Bake at 350°F (175°C) for 1 hour. Eggs poured over the layers must cook through and set, while the crust browns. Too little baking leaves a runny, undercooked centre; the filling needs enough time for the egg to coagulate fully.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream, meat, ham, egg, pepper):
- Asparagusfits about as well
- Potatothe original
- Mustardfits about as well
- Capsicumfits about as well
Fit is the average pairing score against butter, cream, meat, ham, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
