Make the mixture

  1. Season the mashed potatoes with salt and pepper.

  2. Stir in the butter and beat until creamy.

  3. Add the eggs and cream or milk, mixing well.

Bake

  1. Pour the mixture into a baking dish and bake until golden brown.

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 dish and set the soft, fluffy body.
Eggs
Bind the mixture and set it as it bakes, giving the puff its structure.
Butter
Adds richness and a smooth, creamy texture.
Cream or milk
Adds moisture and loosens the mixture for a lighter, softer crumb.

The step that matters

Beating in the eggs and cream or milk. Eggs must be mixed in evenly so they set uniformly as the dish bakes. Overbeating can make the mixture dense and gummy, while undermixing leaves streaks of egg that set unevenly.

Swap the potato

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

  2. Spinachfits about as well

  4. Capsicumfits about as well

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