Sweet Potatoes, Candied

Oven, in the book's wordsA moderate oven

Ingredients

Sweet potatoes
Granulated sugar
Butter

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.

Boil sweet potatoes until tender.
Cut them into thin slices.
Layer the slices in a baking dish, sprinkling each layer with granulated sugar and melted butter.
Add extra bits of butter on top.
Cover and bake in a moderate oven at 350°F (175°C) until clear and rich.
Keep covered until half done.
