Glazed 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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Slice the cold sweet potatoes into 1-inch thick slices.

  2. Season the slices with coarse sea salt and black pepper.

  3. Melt the butter and mix in the sugar.

  4. Dip the sweet potato slices in the butter-sugar mixture.

  5. Arrange the slices in a large pan.

Bake and serve

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

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 dish, becoming tender inside while the outside caramelises.
Butter
Carries the sugar and promotes browning, giving the slices a rich, glossy coating.
Sugar
Dissolves into the melted butter and caramelises in the oven, adding sweetness and a glaze.

The step that matters

Bake in a very hot oven until glossy brown. The sugar and butter coating can burn if the oven is too hot or the slices stay in too long. Watch closely so the glaze turns glossy and brown rather than dark and bitter.

Swap the sweet potato

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

  1. Capsicumfits better
  2. Potatofits about as well
  3. Sweet potatothe original
  4. Mustardfits about as well

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