Sweet Potato Yeast Rolls - active dry yeast

Method

• In a large mixing bowl, dissolve yeast in warm milk, then add 1 teaspoon of sugar & let stand for 5 minutes.
• Add the sweet potatoes, egg yolks, butter, salt, the 1/3 cup sugar & only 2 cups of the flour.
• Beat util smooth, then stir in enough of the remaining flour to form a soft dough ~ All of the last 2 cups of flour might not be used!
• Turn onto a floured surface & knead until smooth & elastic, about 6-8 minutes.
• Place dough in a bowl coated with cooking spray, turning once to coat the top.
• Cover & let rise in a warm place until doubled, about 1 1/2 hours.
• Punch the dough down, then turn onto a lightly floured surface & divide into 30 balls.
• Roll each ball into a 10" rope, then tie each rope into a loose knot.
• Place the knots of dough 2" apart on baking sheets coated with cooking spray.
• Cover & let rise until doubled, about 30 minutes.
• About 15 minutes before the rising is finished, preheat oven to 350 degrees F.
• In a small bowl, beat egg whites & cold water. Brush this egg wash over the rolls, then sprinkle each with sesame seeds.
• Bake for 15-17 minutes or until lightly browned.
• Remove from pans to cool on wire racks.
