Note: this recipe yields 16 small buns. When the dough is ready, divide into 16 portions. Each weighing around 50g. Flatten each dough. Wrap 1-2 tbsp of filling inside each rolled dough. Repeat the rolling & wrapping steps with the rest of the dough & filling. wrap each bun up neatly & lightly shape/roll into round ball. Avoid pressing buns hard when rolling them into smooth balls. Place each bun on each paper cup liner or a small piece of baking paper with its seam sides down.

Rest the buns in warm mist for 40mins or until the dough look puffy.

In the meantime, prepare the steamer- set water to boil for steaming later. Steam bun over medium heat for abt 15-20mins until done. The steaming time varies if multiple layers of buns are steamed. The layer that is closest to direct steam will take lesser time to cook (around 15mins). When ready, remove the buns from the steamer & serve warm.

Left over can be refrigerated or kept in the freezer with cling wrap & cover. Allow buns to cool completely at room temperature before freezing. Wrap each bun in small bag before storing in the freezer. To consume, steam until hot & serve. Alternatively, refrigerated buns can also be microwaved for 15-30sec.
