No but mine were frozen and sometimes they freeze them in an odd solution. I wasn't sure about these. There are some I have bought from Aldi frozen that are great to just thaw without a soak. These I just wanted to be sure. When cooking from fresh I will rinse and pat dry sometimes just to be sure there are no sandy or shell particles attached. That's just me.I have eaten scallops, but I have never cooked them. Is it standard procedure to soak scallops before cooking them?
