In a small bowl, combine warm water, sugar, and yeast. Let it sit for about 5 minutes until frothy.

In a mixing bowl, combine flour and salt. Add the yeast mixture and milk, mixing until a dough forms.

Transfer the dough to a floured surface and knead for about 8-10 minutes.

Place the kneaded dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour or until doubled in size.

Once risen, punch down the dough and divide it into 12 equal pieces. Roll each piece into a ball, then flatten into discs.

Cut small squares of parchment paper for each bun and place them underneath.

Arrange the buns in a steamer basket, leaving space for expansion. Steam over boiling water for about 10-15 minutes until fluffy.

Once cooked, remove the buns and let them cool slightly. Fill with your favorite ingredients and savor.
