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

  1. Preheat the oven to 400°F (200°C).

Make the mixture

  1. In a bowl, combine mashed potatoes, butter, salt, pepper, onion juice, and egg yolks.

  2. Gently fold in the beaten egg whites.

  3. Spoon the mixture onto a baking sheet or into a frying pan.

Brown

  1. Brown in the oven or on the stovetop until golden.

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 puffs and give them a soft, tender interior.
Butter
Adds fat for richness and a softer, moister texture.
Egg yolks
Enrich the mixture and help bind it with moisture and fat.
Egg whites
Whipped air folded in gives the puffs lightness and lift.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air bubbles that give the puffs their lightness. Stirring vigorously knocks that air out, so the puffs turn dense instead of light.

Swap the onion

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

  1. Chivefits better
  2. Asparagusfits better
  3. Capsicumfits better
  4. Onionthe original

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