Mix the ○ ingredients together, and knead well for 5-10 minutes until the surface is smooth. It's faster to knead by hand than in a bread machine. Let the dough rise (1st rising): put the dough in a lightly oiled bowl. Heat up a steamer until steam is rising. Turn off the heat, and put the dough in the bowl in the steamer until doubled, about 15 to 20 minutes.
