Glaced Sweet Potatoes

Oven, in the book's wordsA very hot oven

Ingredients

Directions

The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Slice the cold sweet potatoes into 1‑inch thick pieces.

  2. Melt the butter and mix in the sugar.

  3. Dip the potato slices into the butter mixture.

  4. Place the slices on a large pan.

Bake and serve

  1. Bake in a 400°F (200°C) oven for 12 minutes or until glossy brown.

  2. Serve hot.

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

What each ingredient does

Sweet potatoes
Provide the starchy base that takes on the glaze and softens as it bakes.
Butter
Carries the sugar and coats the slices, adding richness and helping them brown.
Sugar
Sweetens the butter coating and caramelises in the oven to form a glossy, browned surface.

The step that matters

Bake until glossy brown. Sugar caramelises only at sufficient oven heat, so the glaze can burn if left too long or stay pale if underbaked. Watch the color rather than relying on time alone.

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.
