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

  2. Grate the sweet potatoes and place them in a bowl.

Make the custard

  1. In another bowl, beat the eggs and mix in the sugar, salt, and flavoring.

  2. Add the flour mixed with a little milk to the egg mixture.

  3. Combine the sweet potatoes with the egg mixture and add the quart of milk to thin it out.

Bake

  1. Pour the mixture into a baking dish and bake 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 pudding, with starch that softens and sets as it bakes.
Eggs
Bind the mixture and help it set into a firm, sliceable custard when baked.
Sugar
Adds sweetness and helps balance the earthy flavor of the sweet potatoes.
Flour
Thickens the custard slightly and helps it hold together as it sets.
Milk
Adds moisture and creaminess, thinning the batter so it bakes evenly.

The step that matters

Bake until set. Eggs set when heated to roughly 160°F, so the pudding must bake until the center is firm, not just the edges. Underbaking leaves a loose, watery custard, while overbaking can make it curdle or dry out.

Swap the sweet potato

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

  1. Sweet potatothe original
  2. Arrowrootfits about as well
  3. Beetrootfits less well
  4. Capsicumfits less well

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