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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Stir melted butter into the mashed potatoes until well combined.
Beat the mixture to a white cream consistency.
Add the beaten eggs and cream or milk, mixing well.
Season with salt to taste.
Bake
Pour into a deep dish and bake at 400°F (200°C) until nicely browned.

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 puff and give it a soft, light body.
- Eggs
- Bind the mixture and set during baking to give the puff its structure.
- Butter
- Adds richness and fat, softening the texture and aiding browning.
- Cream or milk
- Adds moisture and makes the mixture smoother and looser for a lighter result.
The step that matters
Beating to a white cream consistency. Beating incorporates air into the potato mixture, which helps the puff rise and become light. Under-beating leaves it dense, while the eggs set in the oven to hold that airy structure.
