How to make purple sweet potato cake

1.Purple sweet potatoes are steamed and pureed! I used two small purple sweet potatoes

• 

  2.After making it into a puree, add flour , white sugar and warm water with yeast! !

• 

  3.Cool into a thick paste, preferably close to solid, because it is too soft It should be sticky when steamed.

• 

  4.Move it into another container (because it is easier to put some oil in the new container to get it out ), ferment for 1-2 hours until doubled in size.Steam for 30 minutes and simmer for 5 minutes.ok

  5.The pot was too short, and it stuck to the rice cooker and covered it after being adjusted! 

  6.Reflection~ I feel like there is too little flour, I should add more flour, because I feel like The cake has more of a purple sweet potato texture than pasta.And it’s too sticky because it’s so soft.Add more flour, add more flour ~~
