[novice Zero Failure] Milky Purple Sweet Potato Mantou
1.
Wash the purple sweet potato and steam it (or use a microwave oven).
2.
Remove the purple potato skin and pound it into a puree with a rolling pin (a longer time is better).
3.
Use a container with a little boiled water to thoroughly rinse the milk powder, let it cool to about 35 degrees (not hot), put the yeast in the mixture and let it stand for 5 minutes.
4.
Take a large basin, add flour, pour in the yeast water, stir it into a floc with chopsticks, and then add the mashed purple potato.
5.
Knead the flour into a dough (if it feels too dry when kneading, dip your hands in water and continue to knead, if it is too thin, sprinkle and add the flour). Knead vigorously until the dough is uniform in color (this is a long time), and when the surface is smooth, let it rest for 15 minutes.
6.
Tear the dough into several small doses.
7.
Sprinkle a thin layer of flour on the panel, knead each small agent until the surface is smooth, then form a dough, and mold it into a green body on the panel.
8.
Put water in the steamer, brush a light layer of oil on the steamer, place the green body on the steamer at intervals, and let it ferment for 1 hour on its own. After 1 hour, its volume will be twice as big, steam it on high heat for 20 minutes, turn off the heat and let it stand for five minutes, open the lid, and serve. (In cold weather, the fermentation time can be extended appropriately).
9.
After the operation is complete, remember to steam for 20 minutes and turn off the heat, and then be sure to let it stand for five minutes before opening the lid.
