This is pretty easy but it makes a grand entrance.
3 pounds sweet potatoes
¼ cup brown sugar
3 egg whites, room temperature
¾ cup sugar
1 teaspoon cinnamon
Preheat oven to 400 degrees.
Bake potatoes for 1 hour. Cool, peel and dice. Toss with brown sugar and spread over bottom of 2-quart baking dish. Cover and bake for 25 minutes.
In the meantime, beat egg whites on high until soft peaks form. Gradually add sugar, continuing to beat, until stiff peaks form. Gently fold in cinnamon.
Heat broil to high. Carefully spoon meringue over potatoes and toast under broiler, watching carefully to prevent burning. This will take a few minutes tops!
