Found it in my Skippy Super Chunk today. It was hard inside and out (inside was also shiny and a looked oily, which you can see clearly if you zoom in), but it did crumble under a decent amount of pressure. It was briefly in my mouth (I didn’t bite down on it, I just picked it out of the PB with my spoon, used my mouth to get it off the spoon, and spit it out) and there was no weird taste, the texture on the outside felt exactly like the other peanut pieces. Same smoothness, clearly felt like a peanut. Color is SUPER dark brown, nearly black, with like a little tiny hint of reddish. Same color as burnt spots on other peanut pieces. Literally the EXACT same color. No unusual or strange smell either. I tried looking it up and what I found is that it’s almost guaranteed to be a severely burnt peanut sliver or core, and the shape was correct for that when it was whole, but I’m paranoid and have a severe case of ARFID so I have to ask actual people. Please only reply with genuine answers, absolutely no jokes about it being something gross or unsafe or anything, please, I am begging you. I have ARFID/severe food anxiety and this is freaking me out.
