Prawn vs Shrimp?
I guess the two words are used pretty interchangeably, but does anyone know of a place in Boston that serves actual prawn, as opposed to shrimp just being called prawn to sound worldly?
In the olden days, prawns were freshwater, shrimp were saltwater.
Today, most of the freshwater "prawns" are farm raised, Tiger Shrimp is a very common/popular farm raised freshwater prawn. Red Lobster sells tons of farm raised freshwater prawns.
If I had my choice, I would look for wild shrimp.
In my experience it's primarily a cultural thing - while there may be some official scientific differences between the various varieties of these wiggly critters, (viz. the Australian government link Blumie provides), we Americans call them all shrimp while our British cousins call them all prawns. In fact according to that Aussie doc, what we eat in shrimp cocktails are in fact actually prawns!
And when Paul Hogan spoke the, now famous, line for an Australian Tourism Commision TV spot; "I'll slip an extra shrimp on the barbie for you!" he was altering it for U.S. consumption. (sorry). Any self-respecting Aussie would have said "prawn".
