Purple Sweet Potato Steamed Buns (Mantou) Recipe


Yields:  12 buns

INGREDIENTS:

250g pau flour (low protein flour)
120g mashed purple sweet potato (from about 200g raw poato)
35g caster sugar (please use 60g if you prefer sweeter.  I used brown sugar)
1 tsp instant yeast
3/4 tsp double acting baking powder
15g coconut oil or any vegetable oil
120g water

12 pieces (3” X 3”) baking parchment paper


METHOD:

Mashed Purple Sweet Potato
  1. Wash, peel and cut the potato into small pieces.
  2. Steam the potatoes till soft, about 15 to 20 minutes at medium heat at normal steamer.  For Panasonic Cubie Oven, please steam at Steam-Med for 15 minutes.
  3. Mash the steamed potatoes with a potato riser. If you do not have potato riser, you may push the potatoes through a sieve.  
The Buns:
  1. Mix all ingredients in the bowl of electric stand mixer. Knead the dough until all come together, around 8 minutes with the dough hook attached.
  2. Cover the bowl with cling wrap and let the dough rest for 30 - 45 minutes or until double in size at a warm place. I normally leave the dough in the same bowl after kneading and cover the bowl with kitchen towel for proofing.  For Panasonic Cubie Oven, please select fermentation at 40C for 30 minutes.
  3. Lightly dust the working surface with flour. Gently punch down the dough to deflate. Cut and divide into 12 equal portion. 
  4. Shape each portion into a ball.  Place each bun on a parchment paper that prepared earlier. Spread the buns on the bamboo steamer about inch apart.  For Panasonic Oven, place the buns on the wire racks.  6 buns on each rack.
  5. Let the buns rise until 60% - 70%  from its original size about 15 to 20 minutes in semi warm area.  For Panasonic Cubie Oven, please select fermentation at 40C for 15 minutes.
  6. Prepare the steamer, wrap the steamer cover with a clean cloth.  This will prevent steamer water dropping on the bun, to get a smooth skin.  Steam for 8 - 10 minutes over the medium heat.  For Panasonic Cubie Oven, please steam at Steam-Med for 10 minutes.
  7. Once it’s done, open the cover slightly to release the heat for few minutes. Transfer the bamboo steamer away from the water and let it stand for another few minutes before removing the cover. With this, the buns will not shrink after cooling down. For Panasonic Cubie Oven, please open the door slowly.
