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 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
Mix the mashed potatoes with butter, cream, loaf sugar, beaten eggs, candied peel, and nutmeg or cinnamon until well combined.
Fill and bake
Preheat the oven to 400°F (200°C).
Fill patty pans or saucers lined with pastry no more than halfway.
Sprinkle fine sugar on top.
Bake for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the filling and help it set into a tender, sliceable custard as it bakes.
- Butter
- Adds richness and fat, giving the filling a softer, smoother texture.
- Mashed potatoes
- Provide the bulk and body of the filling, giving it a soft, moist crumb.
- Cream
- Adds moisture and richness, keeping the filling soft and smooth.
- Loaf sugar
- Sweetens the filling and helps it brown lightly in the oven.
