Yes she explained that. She said that salt water has killed most of the trees. So it was getting hard to find (at least where she lives.) Yhe gumbo she made was seafood gumbo and it was like really clear. She gave us a recipe.File is actually dried and ground up leaves from the sassafras tree (the roots of the tree are what gives root beer its flavor).
My wife went to the grocery store to look for file. I told her she was wasting her time. She asked for it and they told her they didn't know what she was talking about.
Again I told her there was 0 chance of her finding file in the grocery store.
That's when she found it in the seafood section.
I think she used her superpower on the people that worked there and they printed a label and stuck it on a bottle just to get shut her up.
