Pan-baked Sweet Potatoes

Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Prepare

  1. Cut cold boiled sweet potatoes into ½ inch slices.

  2. Layer the slices in a baking pan, adding a thin layer of sugar between each layer.

  3. Sprinkle with salt and pepper.

  4. Add ½ cup water and cover the pan.

Bake and serve

  1. Bake in a 400°F (200°C) oven for 20 minutes.

  2. Remove the lid and bake for an additional 30 minutes until clear and transparent.

  3. Serve in the baking pan.

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.

Sugar and pepper barely smell alike, yet cooks put them together in 19,401 recipes: they work on texture and structure more than aroma.

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, softening into tender layers as they bake.
Sugar
Sweetens the dish and caramelizes slightly into a syrup that coats the slices.
Water
Creates steam under the lid, helping the potatoes cook through and stay moist.

The step that matters

Remove the lid and bake for an additional 30 minutes until clear and transparent.. Covering keeps steam in so the potatoes cook through and the sugar dissolves. Uncovering lets the liquid reduce and thicken into a syrup, so the cook must watch for the clear, glossy look rather than simply following the timer.

Swap the sweet potato

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

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

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