Add all the ingredients (in the order listed above) in the bowl of the mixer.Start kneading using the dough hook on low speed and slowly increase to medium-high speed. Knead for 5 minutes, the dough should be soft and smooth.
Cover the bowl with a damp kitchen towel and place it in a warm place to rest and rise for 90 minutes.
Prepare the buns
Once the dough is ready, place it on a floured surface and knead by hand to release the air bubbles for 1 or 2 minutes.
Roll the dough and cut 12 slices.
Take one slice and roll it in your hands to shape a ball.
Place each ball on a small piece of parchment paper.
Steam the Bao Buns
Place the balls on a food steamer with the parchment paper leaving a bit of space between them. Steam for 20 minutes.
Once done, leave them in the basket for 5 minutes to allow them to slowly cool down. Then they can be placed on a cooling rack without the parchment paper.
They can be served immediately or frozen when totally cooled down.
Re-heat after Frozen
Leave to defrost in the counter top for a couple of hours or on the fridge over night. Steam for 5 minutes. They are as good as freshly prepared.
