Refrigerator Sweet Potato Rolls

Ingredients

• 2 medium sweet potatoes (about 2 pounds)
• 2 packages dry yeast (about 4 1/2 teaspoons)
• 1 teaspoon brown sugar
• 1/2 cup warm water (100° to 110°)
• 3/4 cup warm 2% reduced-fat milk (100° to 110°)
• 1/2 cup packed brown sugar
• 1/4 cup butter, melted
• 2 teaspoons salt
• 1/2 teaspoon grated orange rind
• 1 large egg, lightly beaten
• 5 cups bread flour, divided
• Cooking spray
• 1 tablespoon butter, melted
• 1 teaspoon grated orange rind
• 1 tablespoon fresh orange juice

Preparation

1. Preheat oven to 450°.
2. . Place sweet potatoes on a foil lined baking sheet; bake at 450° for 1 hour or until tender. Cut potatoes in half lengthwise; cool to touch.
3. . While potatoes cool, dissolve yeast and 1 teaspoon brown sugar in warm water in a large bowl; let stand 5 minutes. Add milk and next 4 ingredients, stirring until sugar dissolves. Add egg; stir well.
4. . Peel and mash sweet potatoes with a fork until smooth. Stir 1 1/2 cups potato into yeast mixture. Reserve remaining potato for another use.
5. . Lightly spoon flour into dry measuring cups; level with a knife. Add 2 cups flour to yeast mixture; stir until smooth. Gradually stir in enough remaining flour to form a soft dough. Turn dough out onto a lightly floured surface. Knead until smooth and elastic (about 8 minutes), adding just enough remaining flour to prevent dough from sticking.
6. . Place dough in a large bowl coated with cooking spray, turning to coat top. Cover with plastic wrap, and let rise in refrigerator at least 8 hours or up to 3 days, punching dough down as necessary when dough rises to top of bowl.
7. . Coat 3 (9-inch) round cake pans with cooking spray. With lightly floured hands, shape dough into 36 (1 1/2-inch) balls. Place 12 balls in each pan, making sure balls do not touch. Cover and let rise in a warm place (85°), free from drafts, 45 minutes or until doubled in size. (Press two fingers into dough. If indentation remains, the dough has risen enough.)
8. . Preheat oven to 375°.
9. . Uncover rolls, and bake at 375° for 15 to 18 minutes or until golden.
