Measure all of the dry ingredients into large mixing bowl. I used an electric stand mixer.
Measure warm water and oil into measuring cup.
Use a dough hook and mix on medium heat the liquid ingredients into the dry ingredients.
Now that you have sticky dough, continue kneading for 10 minutes on medium speed until it becomes soft and smooth.
Cover bowl with cling wrap and let sit for an hour and half.
Once the dough is ready, punch down and knead for 5 minutes by hand. Then roll dough until it is about 1 cm in height
Use toasted sesame oil and rub on dough with hand, use 3 inch cookie cutter and cut dough in rounds, fold in half and then roll one more time.
Place buns on parchment paper and continue with these steps until you have used up all the dough. Let rise for 20 minutes.
Steam the buns. You can use a steamer basket for this step, I used bamboo, but you can also poke holes in a disposable pie pan. Fill the saucepan 1/3 of the way up with water. Place steamer on top. Lay a layer of parchment paper so the buns do not stick. Steam buns for 12 minutes. Best used right away.
