I do like scallops.I think the fresh"diver"scallops you cn find in high end placed are the best.
For some reason scallops,for the most part,just do not taste as sweet as thy used to.I often get a "baking soda"taste from them.I do know they are being treated with solutions much more often than they used to be-"fresh"scallops are often sold in vacum packed containers containing a brine solution.So unless you can see the shell(and sometimes the roe)frozen are often a better way to go.
Also be aware that a lot of "scallops"found under breading is actually shark or other cheap fish cut and flavored to look like scallops.
