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.

Make the base

  1. In a saucepan, combine mashed potatoes, egg yolks, cream, butter, and salt.

  2. Stir constantly over medium heat until the mixture is light and hot.

Fold and bake

  1. Remove from heat and gently fold in the beaten egg whites.

  2. Transfer the mixture to a buttered baking dish.

  3. Bake in a 350°F (175°C) oven until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 puff and give it a soft, starchy body.
Egg yolks
Add richness and help bind the base into a smooth, custard-like mixture.
Egg whites
Trap air when beaten, which expands in the oven to lift and lighten the puff.
Cream
Adds moisture and richness, keeping the texture tender rather than dry.
Butter
Adds fat for flavor and helps the top brown in the oven.

The step that matters

Fold in the egg whites gently. Beaten whites hold air that expands in the oven to lift the puff. Stirring or mixing hard deflates the foam, leaving a dense, flat result.

Swap the potato

How well each one fits the dish's main ingredients (egg, cream, butter):

  1. Leekfits about as well
  2. Potatothe original
  3. Asparagusfits about as well
  4. Chivefits about as well

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