Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potato Puff
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 the potatoes
Wash the potatoes and boil them until soft.
Peel and mash the potatoes, then put them through a ricer.
Make the mixture
Add salt, pepper, and hot milk, beating slowly while mixing.
Add the beaten egg yolks and fold in the egg whites.
Turn the mixture into a hot buttered dish.
Bake
Bake for 30 minutes at 400°F (200°C).
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
- Potatoes
- Provide the starchy bulk that gives the puff its soft, light body.
- Eggs
- Yolks enrich and bind the mixture, while folded whites lift it as it bakes.
- Hot milk
- Adds moisture and softness, and warm milk blends more smoothly into the mashed potato.
The step that matters
Folding in the egg whites. Whites hold air only if they are folded in gently. Stirring or deflating them removes the air bubbles that make the puff rise and stay light in the oven.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, pepper):
- Capsicumfits better
- Potatothe original
- Asparagusfits about as well
- Spinachfits about as well
Fit is the average pairing score against egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
