I have to say this is the first time I’ve ever seen something like this. Black potato chips!
I was mystified be what the flavor would be. The picture on the bag didn’t help, showing a bowl of potatoes with mayo and pepper. None of those things explain the black color though. It was all solved when I brought them home. It turns out they are covered in squid ink powder. Here’s a photo of the actual chip.
They tasted good, but it doesn’t especially look appetizing.
