Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Puff
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 mixture
In a bowl, mix the mashed potatoes with melted butter until creamy.
Beat the eggs until light and fluffy, then add to the potato mixture.
Stir in the cream, salt, and pepper until well combined.
Bake and serve
Pour the mixture into a baking dish and bake until set and browned.
Garnish with parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the dish and give it a soft, creamy body.
- Eggs
- Set the mixture when baked and add structure and lift through whisked air.
- Cream
- Adds richness and moisture, keeping the interior tender rather than dry.
- Melted butter
- Adds fat for richness and smoothness, and helps the surface brown.
The step that matters
Beat the eggs until light and fluffy. Whisking traps air in the eggs, which helps the puff rise and lighten in the oven. Under-beaten eggs give a denser result, and the eggs must be fully combined so they set evenly.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, cream, pepper, parsley):

- Leekfits about as well
Fit is the average pairing score against butter, egg, cream, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
