Potato Puff

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the base

  1. Combine mashed potatoes, egg yolks, cream, and salt in a pan.

  2. Stir over medium heat until hot.

Fold and bake

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

  2. Transfer the mixture to a greased baking dish.

  3. Bake in a preheated oven at 400°F (200°C) until golden brown.

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 flavor team

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.

    Shared aroma: (e)-2-octenal (fatty, green).

Egg and cream barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed potatoes
Provide the bulk and body of the puff.
Egg yolks
Add richness and help bind the mixture while enriching its texture.
Egg whites
Whipped air structure lifts the puff and sets it as it bakes.
Cream
Adds moisture and softness to the mixture.

The step that matters

Folding in the egg whites. Egg whites hold air only while beaten; stirring them vigorously deflates the foam, so the puff loses its lift. Fold gently so the mixture stays light and rises in the oven.

Swap the potato

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

  1. Spinachfits better
  2. Asparagusfits better
  3. Leekfits better
  4. Potatothe original

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