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 batter

  1. Melt the butter in a bowl.

  2. Beat the egg yolks and mix with the melted butter and milk.

  3. Stir in the flour until well combined.

  4. Gently fold in the beaten egg whites.

Bake

  1. Fill cups half full with the mixture.

  2. Bake at 400°F (200°C) for about 20 minutes.

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.

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

What each ingredient does

Eggs
Egg whites trapped by folding give the puffs their light, airy rise; yolks add richness.
Flour
Provides structure so the batter sets around the rising air as the puffs bake.
Milk
Adds moisture and liquid that turns to steam in the oven, helping the puffs rise.
Butter
Adds fat and richness, contributing flavour and a tender crumb.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air only when beaten and kept intact. Stirring or deflating them vigorously knocks out that air, so the puffs will rise less.

Swap the walnut

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

  1. Almondfits better
  2. Walnutthe original
  3. Pecansfits about as well
  4. Milletfits about as well

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