Virginia Sweet Potatoes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Boil the sweet potatoes for 20 minutes.

  2. Remove from heat, peel, and cut into thin slices.

Assemble and bake

  1. Layer the potatoes in a dish, sprinkling sugar and a little cinnamon between layers, and make the last layer sugar.

  2. Melt the butter in the hot water and pour it over the top.

  3. Bake in the oven at 350°F (175°C) until brown.

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 a tender, starchy layered texture.
Sugar
Adds sweetness and caramelizes on the surface to create browning.
Butter
Adds fat and richness, giving the topping a smooth, savoury mouthfeel.
Cinnamon
Contributes warm aroma and flavour that complements the sweet potatoes and sugar.

The step that matters

Bake in the oven until brown. Sugar browns and caramelizes only with sustained oven heat. Pulling the dish too early leaves the top pale and the sugar syrupy rather than golden.
