I bought two 2-pound bags of frozen 41-50 count/pound shrimp. When I thawed them in cold water, one bag's shrimp all sank and the other bag's shrimp all floated.
Bag 1 Bag 2 buoyancy sink float color more white slightly brownish rinsing clear frothy marking 66H/15TT/976 668/21TT/0H354
I assume one of them is not nearly so fresh as the other, or possibly has been frozen and thawed multiple times. I did some searching but couldn't find any real help.
Assuming that one is not so fresh, I would like to return it to the store. But which one? I'm guessing the floating and darker color indicate a more advanced state of decomposition, but your input is appreciated. I'd like to have ammunition at the store in case they question me.
