bitter pistachios in Mexico, ok to eat?

I live in Teloloapan, Guerrero, Mexico.  I read an article about some pistachios being bitter from this area and we have a tree here that does give bitter pistachios (at least I think they are pistachios).  Is it still ok to eat them?  Any danger?  Is their anyway to take away the bitterness?  Thanks

IM not positive about pistachios, are they all bitter or just some? The B17/Cyanide in them can be bad if you eat alot of them, just like apple seeds.

As far as I can tell they are all bitter, but do you know why they are bitter?  Missing something?  Thanks

Without knowing the variety it is either ripeness or its just that variety is more bitter. Have people been eating them alot where you are? I wouldnt be a guinea pig until you have researched it some more.

OK, I am not sure of the variety either, they don´t open by themselves like I have read about, all of them are closed, which I would like to know why.  Couldn´t find anything on the internet though and so turned here to see if someone knew anything.  I haven´t eaten a bunch of them, just a few.  Not dead yet, lol.  OK, if someone knows anything let me know.  Thanks

They are not all bitter at all! I am from Italy, that brags to have a unique variety of Pistachios that grow only around the Etna volcano in Sicily. Turkey is another huge exporter. I tasted both and they are just nutty, mild... couldn't quite describe it, but for sure not bitter, not like some almonds can be.

I was talking about the ones from the tree down here, they are all bitter.  Thanks

Haha sorry. I thought it was someone else replying to you and saying that pistachios are bitter.

Never check the forum as soon as you wake up...

Indeed, the area around Mt. Etna is a wonderful area for growing.  It is attributed to all of the abundant minerals that were deposited in the soils when the mountain blew its innards out.  Many other volcanic soils are comparatively rich.
IMHO, the best pistachios are from Iran.  They are small, but have an intense flavor.

I wish I knew what your problem could be, as pistachios are my all time favorite nut!

Are you sure you roasted them enough. I don't know what is making them bitter but roasting gets rid of cyanide. If its tanic acid you can leach it out with water just like an acorn.
