If someone is searching for 'green' peanuts more than likely the reason is because they belong to a relatively exclusive club of people who are very descriminating when it comes to their particular taste for boiled peanuts. Boiling green peanuts instead of dried peanuts will result in a unique flavor that once tasted, the more common and easily found dried boiled peanuts will often no longer be quite as satisfying.
The problem is they are difficult to come by as green peanuts are very perishable. Once harvested there is only a brief period they can be stored even if refrigerated. Also,you must get them in season which in the south is usually early fall to around mid-November as a rule. This being the case the green peanuts are sold rather quickly or dried to prevent loss.
Green peanuts is a term simply meaning the peanuts have just been harvested and nothing has been done to them. They are not green in color but actually white as in this photograph.
Ever heard some say "Ewww,why would anyone boil peanuts?" Well at our roadside stands in South Carolina we do and all the time. Usually it's someone from New Jersey or Ohio or some other far away distant land where they keep voting the wrong people in office.
The same people are also wrong about peanuts. We think they got confused by the nut at the end of the word Peanut. What idiot would boil a macadamia or maybe a cashew? Wow,was the south always smarter?
Truth is these are not nuts these are beans just like pintos or garbanzos or pole. We would like to ask..."How do you cook these?" Of course you boil them. We highly recommend these folks stop depriving themselves of the best tasting boiled bean (lagume) out there. The delicious world famous boiled peanut!
