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 ↓
Potatoe Cheesecakes
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Boil the potatoes until tender.
In a marble mortar, beat the lemon peel with the sugar.
Add the beaten potatoes and melted butter mixed with a little cream.
Mix well and let the mixture cool.
Fill and bake
Fill patty pans with the crust, filling them slightly more than half full.
Sprinkle double refined sugar on top before baking.
Bake in a 400°F (200°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the filling, giving it a soft, dense texture.
- Lemon peel
- Adds bright citrus aroma and flavour to the filling.
- Sugar
- Sweetens the filling and helps give the top a light browning.
- Butter
- Adds fat for richness and a smooth, tender texture.
The step that matters
Let the mixture cool before filling. Cooling the filling keeps warm butter from softening the pastry before it reaches the oven, helping the crust bake up crisp rather than soggy.
Swap the lemon
