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 Cheese Cakes
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, mix the mashed potatoes, lemon peel, sugar, and butter until smooth.
Add enough cream to achieve a creamy consistency.
Assemble
Roll out puff pastry and cut into rounds.
Place a spoonful of the potato mixture on each round and fold over.
Seal the edges and place on a baking sheet.
Sprinkle loaf sugar over the tops before baking.
Bake
Bake for 20-25 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the filling and give it a soft, smooth body.
- Butter
- Adds fat for richness and a tender, smooth texture in the filling.
- Sugar
- Adds sweetness and helps the pastry tops brown in the oven.
- Lemon peel
- Adds bright citrus aroma and flavour to the potato filling.
- Cream
- Adds moisture so the potato mixture becomes creamy and spreadable.
The step that matters
Seal the edges well. Sealing traps the filling inside the pastry. If the edges open, the moist filling can leak onto the baking sheet and scorch while the pastry stays pale.
Swap the lemon
How well each one fits the dish's main ingredients (potato, sugar, butter, cream):
- Vanillafits better

- Lemonthe original
Fit is the average pairing score against potato, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
