Dissolve the 2 teaspoons of yeast with 6 teaspoons of warm water (32-35 °C) and set aside for about 5 minutes or you start to see the yeast begin to bubble.
In a mixing bowl with a hook, attachment and add the flour, water, salt and yeast, and mix on low speed for 5 minutes.
Increase the mixing speed and mix for about 3 minutes or until the dough is smooth and well developed.
Once the dough is mixed, transfer it to a greased bowl and cover with plastic.
Rest the dough in a warm spot for 60 minutes or the dough doubles in its size.
Transfer the fermented dough onto a floured working surface and divide it into 2 equal parts.
Shape each dough piece into a 1-inch wide log.
Cut off the end pieces of the shaped dough and using a bench scraper or knife cut small pieces at 3/4 of an inch wide.
Space out the cut dough pieces into the top of the steamer and cover with lid and proof for about 30-40 minutes.
Add water to the double boiler and place the top steamer pot on top with lid on.
Steam the buns for about 20-25 minutes or until soft and fluffy.
Turn heat off and leave steamed buns covered for about 5 minutes.
Carefully remove the lid and place steamed buns onto the serving plate.
Serve and enjoy.
