In the process of blanching frozen squid, using hot water can thaw squid faster and make it easier to cook. Hot water can quickly transfer heat to the inside of squid, so that it can be thawed quickly, and at the same time, it can kill bacteria on the surface of squid. In addition, the use of hot water can also help the squid to maintain a fresh and tender taste and avoid the squid from hardening due to overcooking. Therefore, blanching with hot water is the best way to freeze squid.
