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

  1. Preheat the oven to 350°F (175°C).

Make the mixture

  1. In a bowl, mix the mashed potatoes with melted butter until creamy.

  2. Beat the eggs until light and fluffy, then add to the potato mixture.

  3. Stir in the cream, salt, and pepper until well combined.

Bake and serve

  1. Pour the mixture into a baking dish and bake until set and browned.

  2. 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):

  4. 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.
