I always thought all shrimp in the US, except maybe a regional specialty, like the tiny Maine sweet shrimp, and some you get fresh on the southern coast, or gulf, were all frozen...It was just a matter of whether you bought them still frozen, or already defrosted.
I usually use frozen, for that reason, cuz they're convenient to have around. I'm not a big shrimp fan. For me, they, along with fillet of sole, are fish for people who don't like fish, but a good lingua franca for me and my non-pescatarian guests. Well, I bought some, defrosted, I thought, at a Chinese market last nite, and when I sauteed them before adding to my dish, they were GREAT! They were flavorfull, and juicy...It kind of changed my mind about things.
Have I been wrong? Are some shrimp fresh? If not, why did these taste so good?
