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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Line pattypans with puff paste.
Make and fill
Mix the mashed potatoes, currants, sugar, butter, and eggs together until well combined.
Spoon the mixture into the lined pattypans.
Bake
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provide the bulk and moisture of the filling.
- Eggs
- Bind the filling and set as it heats, giving it structure.
- Butter
- Adds fat for richness and a tender texture.
- Sugar
- Adds sweetness and helps the surface brown in the oven.
- Puff paste
- Forms a flaky, crisp case that holds the filling.
The step that matters
Bake until golden brown. The eggs set gradually as they heat. Underbaking leaves the filling wet and loose, while overbaking dries and toughens it. Golden brown is the visual cue that the filling has set and the crust has cooked.
