Baked Sweet Potatoes

Ingredients

sweet potatoes
coarse sea salt
sugar
butter

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat the oven to 400°F (200°C).
Peel the sweet potatoes and cut them in half lengthwise.
Rub the cut sides with coarse sea salt.
Place the potatoes in a baking pan, cut side up.
Sprinkle sugar over the potatoes and dot with bits of butter.
Bake until tender.
