Potato Puff

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.

Prepare and mix

  1. Beat the hot mashed potatoes with a fork until very light.

  2. Add the salt, cream, and butter, then mix in the beaten egg yolks.

  3. Gently fold in the beaten egg whites.

Bake and serve

  1. Pile the mixture high in a baking dish.

  2. Bake at 400°F (200°C) for 5 minutes and serve hot.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

Eggs
Beaten whites trap air for lift, and the yolks add richness and help set the puff.
Mashed potatoes
Provide the bulk and soft, fluffy body of the puff.
Cream
Adds moisture and richness, keeping the mixture tender.
Butter
Adds fat for richness and a smoother, more tender texture.

The step that matters

Folding in the egg whites. Beaten whites hold the air that makes the puff rise. Stirring or folding them too hard deflates the foam, so the puff bakes up dense instead of light.

Swap the potato

How well each one fits the dish's main ingredients (cream, egg, 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 cream, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
