Steam milk bread

All-purpose flour     500g
2% milk                   270g
sugar                           5g 
salt                              2g
baking soda                2g
oil                               5g
yeast                    1/2 tbp


Add all ingredients in a bread machine. Mine has a separate compartment to load yeast; otherwise, you may want to separate sugar, salt and yeast. Choose 'dough' option and let it knot and rise for 45 minutes at least. 

Shape the bun and let it rest for another 30 minutes. Steam for 15 minutes.
