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 Puff with Peas
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the cold riced potatoes, egg yolks, milk or cream, peas, seasoning, and cheese if using.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the potato mixture.
Bake
Pour the mixture into a greased baking dish.
Bake until golden brown on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the base, while whipped whites lighten it and give the puff its rise.
- Riced potatoes
- Provide the bulk and soft, starchy body that holds the puff together.
- Milk or cream
- Adds moisture and richness, keeping the interior tender rather than dry.
- Butter
- Adds fat for richness and helps the top brown in the baking dish.
The step that matters
Folding in the egg whites. Whites hold air only when whipped to stiff peaks. Folding gently keeps that air in the batter, so the puff rises in the oven instead of deflating.
Swap the peas
How well each one fits the dish's main ingredients (potato, egg, milk, cheese, butter):

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