I attempted to air fry some sweet potatoes and over cooked them a bit. I noticed that they had black dots all over them which I havent seen before. Is this normal or was there something wrong with the potatoes to begin with?

I bought the store, pre-cut package from the veggie section.

It is on all of them (about 40 pieces) and I havent eaten any yet in case it was some type of mold or other craziness that got air fried

  • Can you upload a clearer picture?

  • The black dots (or any visible dots) were not there on the raw sweet potatoes. It was only after cooking them they appeared.

  • cooking should kill any mold, so it's not a safety problem, just a taste problem.

Those are just burnt or almost-burnt spots where the sugars in the sweet potatoes caramelized a bit too much. It's possible the potatoes are still palatable - taste them.
