Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Cheese Cake
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Line some patty pans with good pastry.
Make the filling
Mix the mashed potatoes, butter, sugar, currants, and peel together.
Add the well-beaten eggs last and mix well.
Fill the patty pans with the mixture.
Bake and serve
Bake in the preheated oven until golden.
Serve hot or cold.

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, giving a soft, moist, tender texture.
- Butter
- Adds richness and fat, contributing moisture and a tender crumb.
- Sugar
- Adds sweetness and helps the filling brown as it bakes.
- Eggs
- Bind the filling and set during baking to give it structure.
- Currants
- Add small pockets of sweet, chewy fruit throughout the filling.
The step that matters
Add the well-beaten eggs last and mix well. Eggs are added at the end so the mixture is not overworked or overmixed. Thorough mixing distributes the eggs evenly so they set uniformly during baking, giving a consistent structure rather than pockets of uneven texture.
