Over here, shrimp are sold boiled in a 'shrimp boil' that consists of several different spices. You can't find water-only boiled shrimp (at least in the last 2 states I've lived in). It's these spices that turn a rays nose away from cooked shrimp.
Good point, most shrimp/prawns sold in the UK are boiled in salt water but there are some available that have added spices so you need to check the ingredients on the packet.Over here, shrimp are sold boiled in a 'shrimp boil' that consists of several different spices.
