Baked Sweet Potatoes

Ingredients

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.

Wash and scrape the sweet potatoes, then split them lengthwise.
Steam or boil them until nearly done, then drain.
Place the sweet potatoes in a baking dish.
Add lumps of butter, sprinkle with coarse sea salt, pepper, and sugar.
Bake in a 400°F (200°C) oven until nicely browned.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
