Potato Pudding

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Mash the cold potatoes well with a fork.

  2. Moisten the mashed potatoes with milk.

  3. Add flour, minced onions, and grease to the potatoes. Mix until well combined.

  4. Transfer the mixture to a baking dish.

Bake and serve

  1. Bake at 350°F (175°C) until brown, about 30 minutes.

  2. Serve hot.

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

What each ingredient does

Cold mashed potatoes
Form the bulk of the pudding and give it a soft, starchy body.
Milk
Moistens the potatoes so the mixture binds and stays tender in the oven.
Flour
Adds structure, helping the mixture hold together as it bakes.
Grease
Adds fat for richness and helps the surface brown in the oven.
Minced onions
Contribute savory flavor and aroma to the pudding.

The step that matters

Bake until brown. The surface needs enough time in a hot oven for browning, which develops savory flavor. Pulling it too early leaves it pale and under-flavored, while overbaking can dry the potatoes out.

Swap the onion

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

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

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