Spicy Yams

Preheat the oven to 200 degrees. Generously grease a baking dish. Make a 2 inch cut in the center of each yam, and bake them until soft, 75 minutes. Remove them from the oven, reduce the temperature to 350 degrees, and yet the yams cool. Halve them lengthwise, and scoop the pulp into a mixing bowl. Discard the skins. Add all of the remaining ingredients, except the parsley and beat well. Taste and adjust the seasoning. Turn the yams into a soufflé dish, and dot them with additional butter. Bake uncovered for about an hour. Sprinkle with parsley and serve.
