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 the mixture

  1. Boil and mash the sweet potatoes.

  2. In a bowl, combine the mashed sweet potatoes, beaten eggs, milk, butter, and salt.

  3. Beat the mixture vigorously until well combined.

Bake

  1. Pour the mixture into a pudding dish.

  2. Bake in a preheated oven at 350°F (175°C) until set.

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

What each ingredient does

Sweet potatoes
Provide the bulk and body of the puff, along with moisture and mild sweetness.
Eggs
Set during baking to give the puff its structure and airy, custard-like texture.
Milk
Adds moisture and softness, helping the mixture bake into a tender custard.
Butter
Adds fat for richer flavor and a smoother, more tender texture.

The step that matters

Beat the mixture vigorously until well combined. Thorough mixing spreads the eggs and fat evenly through the mashed sweet potato, so the puff sets smoothly rather than in streaks or lumps.

Swap the sweet potato

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

  1. Potatofits better
  2. Asparagusfits better
  3. Chivefits about as well
  4. Sweet potatothe original

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