Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Puffs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the mixture
In a bowl, combine cold mashed potatoes, beaten egg white, butter, and salt.
Roll the mixture into balls the size of an egg.
Dip each ball in the egg yolk.
Bake and serve
Place the balls on a buttered baking pan.
Bake at 400°F (200°C) until light brown.
Serve hot.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 puffs and give a soft, moist interior.
- Egg white
- Binds the potato mixture and helps the puffs hold their shape and lighten.
- Butter
- Adds fat for richer flavor and a tender texture.
- Egg yolk
- Coats the outside so the puffs brown richly in the oven.
The step that matters
Dip each ball in the egg yolk. The yolk coating is what browns the surface in the oven. Uneven or thin coating leaves pale patches, so coat each ball fully before placing it on the pan.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
