Ingredients

3 1/2 pounds sweet potatoes (about 7 medium) 

3 tablespoons unsalted butter, room temperature 

1/2 cup packed light brown sugar 

1/3 cup fresh orange juice 

1/2 teaspoon salt 

1/2 teaspoon ground cinnamon 

1/8 teaspoon ground nutmeg 

3/4 teaspoon ground ginger 

2 teaspoons chopped crystallized ginger 

1 teaspoon grated orange peel 

Preparation

Heat oven to 375 degrees. Wash and dry potatoes, and prick skins with a fork in several places. Bake until potatoes are tender, about 1 hour.

Peel potatoes, and discard skin; transfer flesh to the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until smooth, about 2 minutes. Remove, and discard any stringy fibers from paddle. Scrape sides with rubber spatula.

Combine butter and brown sugar; mix about 30 seconds. Add remaining ingredients; mix until combined. Serve immediately.
