Would anyone know of a place where I can buy just prawn/shrimp shells and heads in Los Angeles? I don't want the meat, just the heads and shells, and buying and shelling several pounds of shrimp would be a bit too expensive for me. I wouldn't mind mail ordering them if its not too pricey.
In case you're bemused and confused for my strange prawn-shell lust, my SO has been craving prawn mee (http://ieatishootipost.sg/search/label/Prawn%20Mee), and the stock is made with pork ribs and as many prawn shells and heads that you can get your hands on. The more the better. At home, people usually just save up the stuff until they have enough, but it takes months.
