Chile - Spiced Sweet Potato Tamales
2 tablespoons firmly packed brown sugar
1 tablespoon ground cinnamon
1-1/2 pounds garnet or jewel sweet potatoes, scrubbed and halved lengthwise
1/4 cup lard or additional butter
1 cup fat-skimmed chicken broth
1-1/4 cups dehydrated masa flour
1 tablespoon baking powder
2 canned chipotle chiles, drained and minced
Salt and fresh-ground pepper
20 dried corn husks, soaked (or use bananna leaves)
Scoop flesh from sweet potatoes (discard skins) into a bowl; mash with a fork until smooth.
In a 1- to 2-quart pan over low heat, melt lard. Pour in chicken broth and stir until warm. Add broth mixture to sweet potatoes; mix well. Gradually add masa flour, stirring until well blended. Stir in baking powder and chipotles and season with salt and pepper to taste.
Tear 3 or 4 corn husks into long, thin strips. Lay a whole husk flat on a work surface, smooth side down, with one long edge closest to you. Spoon a scant 1/3 cup filling lengthwise down center of husk. Fold bottom edge over filling and roll up tamale. Tie each end with a thin strip of husk. Repeat until all filling is used.
In an 8- to 10-quart pan, position a rack at least 1 inch above 1 inch of water; bring to a boil over high heat. Set tamales on rack, lower heat to maintain a simmer, cover, and steam until filling is firm, about 1 hour, adding water to pan as needed to maintain 1-inch depth. Remove tamales and let stand at least 10 minutes before serving.
