I ordered a pizza in the evening. The delivery driver brought it to me. I took it and went to the kitchen to eat. When I opened the box, I saw this. I sat there looking at it, but I still can’t understand what it is. Does anyone know what this is? Check the first comment for the answer 👇

 For a few long seconds I just stared, my appetite wrestling with pure suspicion. The “blisters” looked like strange organs trapped under the cheese, smooth and inflated, catching the light in a way that made them seem wrong. I imagined mystery ingredients, a botched recipe, even some kind of contamination. The more I examined it, the more I felt that mix of fascination and dread you get when something looks almost familiar, but not quite safe.
