You seem to know an awful lot about crabs.At the grocery store, it's real easy to tell the difference between imitation crab meat and actual crab meat.
First of all, the package's label will tell you that it is in fact imitation crab meat.
Second, the package's label will tell you what fish was used to make the crab meat. Nine times out of ten, it's going to be pollock, but I have also seen cod.
Third and final, imitation crab meat looks more like crab meat than actual crab meat.
