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.
Prepare
Stir mashed potatoes, melted butter, and salt until creamy.
Add beaten eggs and cream; mix well and lightly.
Bake and serve
Pile mixture into a dish and grate cheese on 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 soft base that holds the puff together.
- Eggs
- Set during baking to give the puff structure and lift.
- Cream
- Adds moisture and richness for a tender texture.
- Melted butter
- Adds fat for richness and a softer, more tender crumb.
- Cheese
- Melts and browns on top, adding flavor and a golden crust.
The step that matters
Mix the eggs and cream lightly. Overbeating incorporates too much air and can make the puff collapse or turn tough. Gentle mixing keeps the texture light while the eggs still bind the mixture.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, cream, cheese):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Onionfits less well
Fit is the average pairing score against butter, egg, cream, cheese. Candidates are from the same food group and used in at least 100 recipes.
