Thawing frozen seafood mix is a lot of work
Any time you cook the seafood mix it will shed moisture, which it has a lot of and probably on the outside of it as well. I love that mix and I just soak it in a bowl of cold water then drain it. If you keep driving the moisture out before you use it, it will be shriveled up and dry. As you simmer it over time, the level of moisture you want to drive out of it will steam off.
