I guess it all has to do with the shrimp you get also...
Being in Florida, you can get Gulf Shrimp, fresh... (YUMMMM)!
Here in the NE, even in the Fish Markets on the docks.... we only get frozen shrimp that have been thawed...
I'd rather thaw the shrimp myself... We don't get real "fresh shrimp" like you can...
Ina Garten only lives about 15 miles from us (as the crow flies)... so she only gets frozen shrimp that has been thawed too!
