The fungus that is not completely soaked can be eaten, but it will be hard and the texture is not good.
The fungus belongs to the soaked food, when not completely soaked on the consumption of words can be, but there will be a hard place, eating will be clucking teeth, and the root of the fungus has not been! If it is soaked, there will be sand, it will be gritty, so consuming unsoaked fungus will appear above.
Personally recommend you a little trick, find a glass bottle, sealing needs to be a little tight, and then first put the fungus in, in the pouring of warm water, shaking for ten seconds, placed on the side of the five minutes can be all soaked, and there will be no soaked position. Is not very simple. Go and test it.
I hope my answer can help you, hope to adopt, thank you.
