Purple sweet potato two-color steamed buns

Overview

I like tinkering with pasta, and I feel happy when I see the steamed buns of different shapes made with my own hands.

Wash the purple sweet potatoes, cut them in half, steam them, let them cool and then peel them
Crush the peeled purple sweet potato, add flour and knead evenly, then add an appropriate amount of water and yeast powder to form a purple sweet potato dough
Then mix it with a piece of white dough and put the two kinds of dough on the balcony to rise
Ripe purple sweet potato dough
Well-risen white dough
Press the two doughs that have risen with a dough press several times to remove the air bubbles inside
in the next step. Overlap the two dough pieces
Roll up
Cut into sections
A group of two overlaps one above the other
Use chopsticks to press out the shape
After everything is done, the second round
Put the second-raised green embryo into the steamer
Bring to a boil over high heat, turn to medium heat and steam for 20 minutes, then steam for 5 minutes
