I was hoping @Kentucky was a baker and we were going to see images of freshly baked bread. Instead he shows Zincolns. At least he's torturing zincolns. I'd use muriatic acid but the oven isn't too bad. Don't forget to release them back to the wild for those error searchers.
On a piece of Al foil, directly under the heater element of an electric oven, set to 450 degrees and remove when it reaches temperature. Then put the Pizza Rolls in...
Crispy...when I was doing "The Silver And Gold Penny" experiment with high school students and the final step is heating the thin zinc coating to make brass on the surface (the "gold"). Done in a bunsen burner flame, the Zincolns would often rupture and the zinc would drip out.
When I was trying out the big Fresnel lens and sunlight on Zincolns, I had at least one POP. Small noise, little puff of grey smoke. The boiling point of zinc is below the melting point of copper. If I had a good vacuum system, I'd consider trying to make Zincoln popcorn.
