Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Potato Puff

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. In a large bowl, combine the mashed potatoes, salt, pepper, celery salt, butter, parsley, and milk.

  3. Beat the eggs separately.

Make the puff

  1. Add the yolks to the potato mixture and fold in the egg whites.

  2. Transfer the mixture to a buttered baking dish.

Bake and serve

  1. Bake until puffed and golden brown, about 25-30 minutes.

  2. Serve immediately.

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

What each ingredient does

Eggs
Egg whites whipped and folded in provide lift, while yolks add richness and help set the custard-like structure.
Mashed potatoes
Form the bulk of the dish and provide a soft, moist base that holds the puff together.
Butter
Adds fat for richness and a softer, more tender texture in the baked interior.
Milk
Adds moisture that loosens the potato mixture and keeps the finished puff tender.

The step that matters

Folding in the egg whites. Egg whites trap air when beaten, and that air is what makes the puff rise in the oven. Folding gently keeps the air in; stirring hard deflates the mixture and the puff falls flat.

Swap the celery

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

  1. Dillfits better
  2. Thymefits better
  3. Nutmegfits better
  4. Celerythe original

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