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

What each ingredient does

Cold mashed potatoes
Provide the bulk and body of the puff, along with moisture and starch for structure.
Eggs
Set as the mixture bakes, giving the puff its structure and a light, custard-like texture.
Milk
Adds moisture and softness, loosening the potatoes so the mixture bakes up tender.
Melted butter
Adds fat for richness, a smoother mouthfeel, and browning on the surface.

The step that matters

Bake until light brown. The eggs set as the puff bakes. Stopping at light brown keeps the centre moist and tender, while overbaking dries it out and makes it tough.

Swap the potato

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

  1. Potatothe original
  2. Asparagusfits about as well
  3. Chivefits less well
  4. Leekfits less well

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