- 1 sweet potato (224 g or 8 ounce)
- 1 tablespoon packed brown sugar (15 g)
- ¾ cup warm milk (180 ml)
- 1 package active dry yeast (1/4 ounce or 7 g)
- 3 green onions, sliced
- 3 tablespoons butter, melted and cooled (45 g)
- 5 cups all-purpose flour (550 g)
- 1 tablespoon salt (15 g)
- Grease two baking sheets. Set aside.
- In a saucepan of boiling water, cover and cook sweet potato until tender for about 15 minutes.
- Drain cooked potato, reserving 1 cup of the cooking liquid. Set aside potato and cooking liquid to cool until lukewarm.
- Peel and mash potato. Set aside.
- In large bowl, dissolve sugar in warm milk and reserved cooking liquid. Add the yeast and let it stand until frothy for 10 minutes.
- Add the mashed potato, green onions, 1 tsp of the cooled butter, 1 cup of the flour and salt into the mixture to make a smooth paste.
- Gradually mix 3 cups of the remaining flour, 1 cup at a time, to make a soft, sticky dough.
- Turn out dough onto lightly floured surface, knead until dough is smooth and sticky, adding enough of the remaining flour as needed. Kneading takes about 10 minutes.
- Place in a greased bowl and turn the dough to grease all over. Cover with a warm moist towel and let it rise in a warm, breeze-free place until it doubles in size, about 1 hour.
- Punch down dough; turn out onto a floured surface. Divide in half. Roll out each piece into ⅓ inch thick.
- Cut each half into individual 3 ½ inch rounds. Stretch each round into slight ovals; fold crosswise and pat edges gently to maintain shape. The rolls should resemble little half moons.
- Place one inch apart on greased cookie sheet. Cover again and let rise in a warm place for about 40 minutes.
- Brush tops with butter. Bake one sheet at a time, in center oven at 400°F, until rolls are golden for about 15-18 minutes.
- Serve warm and enjoy!
