Add the butter and brown it until it turns a hazelnut color and has a nutty fragrance, about 5 to 6 minutes. Add the chopped shallots and allow to cook for about 3 minutes until translucent. Be careful not to burn the butter.
• When the sweet potatoes are cool, scoop out the insides and place in a bowl. Pour the butter and shallot mixture over the sweet potatoes, and mix.
