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.
Prepare
In a bowl, combine cold mashed potatoes, beaten egg white, and salt.
Roll the mixture into balls the size of a golf ball.
Dip each ball in the beaten egg yolk.
Place the balls on a greased baking pan.
Bake and serve
Bake at 400°F (200°C) until golden brown.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mashed potatoes
- Form the body of the puff balls and provide moisture and starch.
- Egg white
- Binds the potato mixture so the balls hold their shape.
- Egg yolk
- Coats the outside so the balls brown well in the oven.
The step that matters
Dip each ball in the beaten egg yolk. An even coat of yolk gives uniform colour when baked. Thin or patchy coverage leaves pale spots, while cold, firm balls hold their shape better during dipping and baking.
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.
