The bitter taste of bamboo eggs comes from the outermost skin of the bamboo eggs. In fact, it has a strong Chinese medicinal flavor. The bamboo eggs sold on the market are actually used to grow bamboo fungus, which is mainly eaten. The dried bamboo eggs sold on the market are just bamboo eggs that cannot mature physiologically. And some people didn't want to throw them away, so they dried them and sold them. Not a good thing!
