Why it works: Potato and milk are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. 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
Make 1 pint of cold mashed potatoes and ensure they are quite moist with milk.
Beat the yolks and whites of 2 eggs separately.
Stir the yolks and salt into the potatoes.
If desired, add finely chopped cooked meat before folding in the egg whites.
Bake
Fold in the beaten egg whites last.
Turn the mixture into a shallow oiled baking dish.
Bake at 400°F (200°C) for 5 to 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the potatoes, while whipped whites lighten the mixture and help it puff.
- Cold mashed potatoes
- Form the body of the puff, and their moisture keeps the mixture soft inside.
- Milk
- Adds moisture so the potatoes stay soft and spreadable when mixed with the eggs.
The step that matters
Fold in the beaten egg whites last. Folding gently keeps the whipped whites' air in the mixture; stirring or deflating them makes the puff rise less and turn dense.
Swap the potato
How well each one fits the dish's main ingredients (milk, egg, meat):
- Potatothe original
- Asparagusfits about as well
- Capsicumfits less well
- Leekfits less well
Fit is the average pairing score against milk, egg, meat. Candidates are from the same food group and used in at least 100 recipes.
