Ingredients
Directions
Prepare and fry
Boil, peel, and cut sweet potatoes lengthwise into slices ¼ inch thick.

Roast
For roasting, pare and wash the potatoes, then salt them.

What each ingredient does
- Sweet potatoes
- Provide the starchy body that softens inside while the outside browns.
- Sweet drippings or butter
- Conduct heat and add fat, helping the slices brown evenly and richly.
- Coarse sea salt
- Seasons the potatoes and draws out surface moisture for better browning.
The step that matters
Frying until golden brown. Sweet potatoes contain plenty of sugar, so they can scorch before the interior is tender. Moderate heat and turning help the surface brown evenly without burning.
