Stuffed Baked Sweet Potatoes

Oven, in the book's wordsA hot oven

Ingredients

Directions

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

Prepare the potatoes

  1. Wash the sweet potatoes thoroughly.

  2. Bake the potatoes until very soft.

  3. Cut a slice from one side of each potato and scoop out the inside.

  4. Pass the potato flesh through a ricer.

Make the filling

  1. Add 3 tablespoons of butter, ½ teaspoon of salt, and enough hot milk to moisten the riced potatoes.

  2. Beat until light and fluffy.

Refill and bake

  1. Refill the potato skins with the mixture.

  2. Bake for 6–8 minutes at 400 °F (200 °C).

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 flesh that forms the main body of the filling.
Butter
Adds fat for richness and a smooth, tender texture.
Hot milk
Moistens the riced potato so the filling becomes light and spreadable.

The step that matters

Beat until light and fluffy. Beating riced potato with butter and warm milk incorporates air and smooths the starch. Overworking or using cold liquid can make the filling gummy or stiff, so keep the milk hot and stop once it is light.

Swap the sweet potato
