Blanching is a very simple process that involves bringing the squid to a boil, then removing the squid and rinsing it under cold water. This process doesn't take long, usually 1 to 2 minutes, otherwise the squid will become too soft and lose its flavor.
Blanching not only removes the fishy flavor and hardness of the squid, but it also helps remove excess water from the squid. This step makes it easier for the squid to absorb the seasonings and spices during the cooking process, which adds to the texture and flavor of the squid.
In short, blanching is an important step in cooking delicious squid that can help remove the fishy odor and hardness of the squid, while also adding texture and flavor to the squid. Whether you are making fried squid or other seafood dishes, remember to blanch them.
