Grated Sweet Potatoes

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Grate the sweet potatoes using a coarse grater.

  2. In a bowl, combine the grated potatoes with sugar and melted butter.

  3. Immediately transfer the mixture to a shallow baking dish, piling it up loosely.

Bake

  1. Bake in a 300°F (150°C) oven for about 30 minutes until it looks like coconut and is orange in color.

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

What each ingredient does

Sweet potatoes
Form the main body of the casserole once baked and softened.
Butter
Adds fat for richness and helps the surface brown as it bakes.
Sugar
Adds sweetness and helps the surface caramelize and turn golden.

The step that matters

Transfer to the dish quickly and pile loosely. Grated sweet potato starts to darken and release moisture once exposed to air. Piling it loosely keeps air pockets so it bakes evenly rather than turning dense and wet.

Swap the sweet potato

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

  1. Sweet potatothe original
  2. Leekfits about as well
  3. Potatofits about as well
  4. Capsicumfits less well

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