I have been experimenting these steamed bun with various recipes and fillings. It's fun and I personally feel that making these buns are very challenging. To get a soft, fluffy and smooth skin buns are the greatest challenges that you have to face. There a few variations with bun flour, softner etc....this recipe is with dough and bread softner. It turned out as what I wanted, soft, fluffy and smooth skin. This time around I used fresh grated coconut as the fillings.
