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

  1. Preheat the oven to 400°F (200°C).

Make the filling

  1. Bake the sweet potatoes until tender, then cut them in half lengthwise and scoop out the insides.

  2. Mash the sweet potato flesh through a ricer.

  3. Add butter and cream to moisten, then season with salt and lemon juice.

Bake and serve

  1. Refill the potato skins with the mixture and bake for an additional 5 minutes.

What each ingredient does

Sweet potatoes
Provide the main body of the filling and the edible skins that hold it.
Butter
Adds fat and richness to the mashed flesh for a smoother texture.
Cream
Adds moisture so the mashed sweet potato becomes soft and spoonable.
