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 Puff
Ingredients
Directions
The book says “a hot 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).
Make the mixture
Season the mashed potatoes with salt and pepper.
Stir in the butter and beat until creamy.
Add the eggs and cream or milk, mixing well.
Bake
Pour the mixture into a baking dish and bake 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
- Form the bulk of the dish and set the soft, fluffy body.
- Eggs
- Bind the mixture and set it as it bakes, giving the puff its structure.
- Butter
- Adds richness and a smooth, creamy texture.
- Cream or milk
- Adds moisture and loosens the mixture for a lighter, softer crumb.
The step that matters
Beating in the eggs and cream or milk. Eggs must be mixed in evenly so they set uniformly as the dish bakes. Overbeating can make the mixture dense and gummy, while undermixing leaves streaks of egg that set unevenly.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, egg, cream):

- Capsicumfits about as well
Fit is the average pairing score against pepper, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
