[RECIPE] Purple Sweet Potato Rose Steamed Buns

Due to COVID-19, I will be staying at home for another 2.5 weeks before going back to work. Now it is the best time to challenge myself to bake/make something new. I have made a Matcha Mochi Bread back in 2018, but I have never made any bread ever since. Today, I am going to make a Rose Mantou, using Fresh Purple Yam. It is easy to make, and it doesn’t require an oven. You only need 6 simple ingredients in this recipe.

One of the ingredients is of course the Fresh Purple Yam. I was lucky to find a few in Superstore, so you might want to keep an eye out for them on your next grocery trip. Otherwise, other ingredients are something you can normally find at home – instant yeast, water, flour, sugar, and cooking oil. The mantous are pillowy soft, and I enjoyed having them with condensed milk.

  • Print


  • 200g Water/Soymilk
  • 25g Sugar
  • 110g Purple Yam, mashed
  • 300g All Purpose Flour
  • 2tsp Instant Yeast
  • 1.5tsp Cooking Oil


  1. Peel and slice the purple yam. Steam and mash the purple yam.
  2. Mix the instant yeast into water/soymilk, along with the sugar. Cover the container with a lid and rest for 10 minutes.
  3. Pour the yeast mixture to the mashed purple yam. Mix well.
  4. Place the all purpose flour in a big bowl. Pour the purple yam mixture to the flour. Mix well using chopsticks.
  5. When the mixture thickens, sprinkle some flour on the countertop and start to knead it into a dough.
  6. Add the cooking oil to the dough. Continue to knead until the dough fully absorbs the oil.
  7. When the dough becomes elastic, it is ready for rising. Cover the dough with a lid and let it rest for 10 to 15 minutes.
  8. Sprinkle some flour to the dough to prevent stickiness. Divide them into 20g per piece. Bring out 5 balls at once, and cover the unused balls with a lid to prevent dryness.
  9. Roll the divided dough into balls and flatten them into a disc.
  10. I prepared a small tutorial for step 10 to 13, as it may be confusing. The video is placed after the recipe.
  11. Each mantou needs 5 discs. The first disc should have the longest diameter. Place the second disc over half of the first disc, and we will do the same for the third and forth disc. Please ensure the diameter of the discs are the same.
  12. Roll up the fifth disc into a tube shape. Please ensure again that its length is the same as the diameter of other discs.
  13. Slowly roll the other discs over the tube.
  14. Slide the finished product in half. Gently fold the outer dough as petals. Place the mantou directly in the steamer and cover with the lid.
  15. The mantous need to rest for another 30 minutes. Do not touch them until they are cooked.
  16. Steam the mantous using medium high heat for 10-12 minutes. Do not open the lid when steaming.
