Cook the sweet potatoes in a saucepan of boiling water for 25 minutes.
Drain and mash the hot sweet potatoes with the 1/2 cup sugar and the
butter, canela, cream and half of the orange peel.

Preheat the oven to 325 degrees. Grease a baking dish and sprinkle
with 1/2 teaspoon sugar and the remaining orange peel. Spread the sweet
potato mixture in the dish and bake for 10 minutes. Garnish with the
raisins and let cool.
