If the nut looks slightly deformed and/or is dark in the shell and the nut inside is dark, it is not because it was roasted. It's because there is a worm inside. There's often a bit of web inside as well. That is not a part of the pistachio. That is the worm's web.

I know. It is traumatic, but you know now and I'm glad that you do.

The only bad thing about realizing this about pistachios is that I have personally struggled to eat them since, and they used to be one of my favourite snacks. Hopefully, you will be more resilient than me.

I read it, but I'm going to try and forget it as soon as possible.
