Why it works: Potato and cream are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,481 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Potato Puff
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Boil and mash the potatoes.
Add the eggs, sweet cream, and salt. Beat thoroughly.
Bake
Bake in a 400°F (200°C) oven for 15 minutes or until hot and browned on top.
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.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: (e)-2-octenal (fatty, green).
Egg and cream barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the puff its soft, fluffy body.
- Eggs
- Bind the mixture and help it set and rise as it bakes.
- Sweet cream
- Adds moisture and richness, keeping the puff tender.
The step that matters
Beat thoroughly. Beating the mashed potatoes with eggs and cream incorporates air and evenly distributes the binders, so the puff rises lightly instead of turning dense and uneven.
Swap the potato
How well each one fits the dish's main ingredients (egg, cream):
- Spinachfits better
- Asparagusfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, cream. Candidates are from the same food group and used in at least 100 recipes.
