The Publix by me...but the publix less than 2 miles away from that one doesn't let you grind it yourself.
In the Deli or Bakery they sell little Publix containers of peanutbutter. They're soft plastic containers, easily bent, if you know which ones I mean. All those containers of peanutbutter are ground up by Publix on a daily basis and I believe they add nothing but peanuts. If they do (I do it myself so Im not sure), every Publix bakery has that machine so you can ask them to make a batch for you with nothing else.
That's the PB I put in my dog's kong toys sometimes too bc I know it doesn't have any artificial bullshit.
