Health guidance: Hello, you can not eat, some of the black stuff to squeeze out before you can, that is the viscera and intestines can not eat all the mud is shit, and then use a rolling pin or something to the mussels of the axe foot is a semi-circular hard that knock a knock, so that it is easy to cook! Clean up with salt a few times, rinse with water, and then put in boiling water blanch a little bit, fishing out clean and cut to cook soup! This is also a favorite of mine! I often buy a little more in the spring when there are more packaged up and frozen to eat slowly!
