Chinese steamed buns
I have had luck with this:
In a alrge bowl mix 2 tsp. dried yeast (I like SAF instant)with 1 cup of war water, 1/4 C. sugar (add more if you like sweeted bao)and 1 1/2 C. cake flour. Mix it up well and let it stand for an hour covered in a warm place.
Then stir in 1/ 2tsp salt and 1 Tbs. rice vinegar. Then 2 C. cake flour, 1 Tbs. baking powder (look for Rumford baking powder if you don't have it, it has no aluminum and tastes better)1/4 tsp. baking soda and 1 Tbs. shornening. Stir and knead the dough. It will be somewhat sticky but work with it and then grease another bowl and put the dough cover it anbd let it rise for about an hour. That should make enough dough for about 24 bao.
