Why it works: Potato and olive are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 6,458 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Potato 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
Preheat the oven to 350°F (175°C).
In a dish, combine the potatoes, pepper, salt, butter, and olive oil.
Add enough water to cover the potatoes.
Assemble and bake
Cover the dish with pastry.
Bake until the pastry is golden and the potatoes are tender.

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, turning soft and starchy as they cook through.
- Butter
- Adds richness and flavour, and helps the potatoes taste full and savoury.
- Olive oil
- Adds fat and moisture, helping the potatoes stay tender and coat evenly.
- Pastry
- Forms a sealed top that traps steam and browns to a golden, crisp crust.
The step that matters
Bake until the potatoes are fully tender. The pastry seals the dish, so the potatoes cook mainly by trapped steam and heat. Pulling the dish early leaves the centre firm, while the top may already look done. Check the potatoes, not just the crust colour.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, olive):
- Capsicumfits better
- Tomatofits better
- Potatothe original
- Eggplantfits about as well
Fit is the average pairing score against pepper, butter, olive. Candidates are from the same food group and used in at least 100 recipes.
