Baked Stuffed Yams - cooking recipe

Ingredients

4 yams, medium-sized
2 tablespoons unsalted butter
1/2 teaspoon salt
1/4 teaspoon pepper
1 1/2 teaspoons orange zest, minced
2 egg whites
1/8 cup parmesan cheese, grated

Preparation

Preheat oven to 400 degrees F & set out a shallow baking pan.
Scrub yams well & pat dry.
Rub each with butter or salad oil, then pierce skin with a fork & place in the baking pan.
Bake until soft, about 30-40 minutes, OR bake at a lower temperature along with meat for about 1 hour. Remove from oven.
While yams are cooling slightly, beat 2 egg whites until stiff, then set aside.
When yams have cooled enough to handle, cut a slice off a side of each yam so that you can scoop out the pulp into a mixing bowl & leaving about a quarter-inch thick shell.
To the pulp, add butter, salt & pepper & orange zest, beating to mix thoroughly.
Fold in beaten & stiff egg whites.
Stuff this filling back into the yam shells & sprinkle tops with Parmesan cheese.
Return to a 350 degree F oven & bake another 10-15 minutes before serving.
