Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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 milk, butter, lemon zest, and sugar in a clean saucepan.
Heat gently until butter is melted.
Gradually add boiled potatoes.
Beat mixture until light and smooth.
Stir in beaten egg yolks.
Whisk egg whites to a firm froth.
Fold egg whites into mixture.
Bake and serve
Grease small patty pans with butter.
Fill pans with mixture.
Bake in a preheated oven at 400°F (200°C) for about 20 minutes.
Sift powdered sugar over the puffs.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a firm froth, they trap air that lifts and lightens the puffs as they bake.
- Egg yolks
- Add richness and help set the custard-like structure of the puffs.
- Boiled potatoes
- Dry, floury potato adds body and a tender, light crumb to the mixture.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Fold in the egg whites. Whisked whites hold the air that makes the puffs rise. Folding gently keeps that air in; stirring or deflating the batter leaves dense, flat puffs.
Swap the potato

Fit is the average pairing score against milk, butter, lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
