Caramelized Sweet Potatoes

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the potatoes

  1. Boil the sweet potatoes in 2 quarts of hot water until tender.

  2. Peel the potatoes and arrange them in a shallow baking dish.

Make the sauce and bake

  1. Boil 1 cup of water and brown sugar together for 10 minutes.

  2. Sprinkle salt and cinnamon over the potatoes and add the butter to the sauce.

  3. Pour the sauce over the potatoes and bake at 350°F (175°C) until nicely browned.

  4. Serve in the dish in which they were baked.

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

What each ingredient does

Sweet potatoes
Provide the soft, starchy body of the dish that the sauce coats.
Brown sugar
Adds sweetness and, as it heats, caramelizes and thickens the sauce into a glaze.
Butter
Adds fat for a richer flavor and a glossier finish on the sauce.

The step that matters

Bake until nicely browned. Sugar caramelizes as it heats, so the glaze needs enough time in the oven to darken and thicken. Pull it too early and the sauce stays thin and pale; leave it too long and the sugar can scorch.
