These are reaaaaaaaaaally fluffy. These bun wrappers are not too heavy, but not too light and slightly sweet. Put whatever you would like in them!
This is the dough I like to make when preparing meat buns.
Translator's note: 551 Horai is a restaurant chain in Japan that is famous for it's meat buns.As you can see from the picture, the seam is facing down. I recommend this trick to beginners, since it prevents the buns from splitting open.
Enjoy Japanese food around the world.
