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 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 batter
Combine the mashed potatoes and melted butter in a bowl, beating until creamy.
Add the beaten eggs and cream, mix in the salt, and beat well.
Bake
Pour the mixture into a baking dish and spread butter over the top.
Bake at 400°F (200°C) 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
- Provide the bulk and starchy base that gives the puffs their body.
- Eggs
- Add structure as they set during baking, holding the puffs together.
- Cream
- Adds moisture and richness, keeping the mixture soft and tender.
- Melted butter
- Adds fat for richness and helps the top brown during baking.
The step that matters
Beating the eggs and cream into the potatoes. Eggs must be fully blended so they set evenly as they bake. Uneven mixing leaves pockets of unset egg or dense spots in the puffs.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, cream):
- Leekfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits about as well
Fit is the average pairing score against butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
