Fresh squid tastes delicious
Use your finger to press the squid body. Fresh squid usually has firm and highly elastic meat. That is, after pressing your hand in and releasing your hand, the ink quickly returns to its original state. If it is not fresh squid, the meat is usually a bit soft and mushy, especially the elasticity is not high, so when you release your hand, the squid body will be indented for a long time before returning to its original state.
