Thanks for that tip. Never heard about red legs and iodineThanks Chris! I like all shrimp, but if I had my preference, it would be 16-20 count inshore shrimp. Offshore shrimp can get too much iodine in them and that makes the meat a little more bitter instead of sweet. The legs tell the tail (no pun intended)......the more red they are-the more iodine in the shrimp. And if you look at the ones I cooked, you will notice the red legs. Might explain why they sat in the freezer for a year.......
