Cool. I’ll have to try engraving. Scoring definitely was surprisingly clean.
I’m not going to go into food safety. That’s your business. But keep something in mind… Lasered stuff doesn’t typically taste good. Now, to be honest, I ate the chocolate bar I cut the other night just to see how bad it was. To me, it wasn’t so bad. Definitely a crispy texture on the cut edges and it tasted burnt there. But it was a little burnt taste mixed in with Hershey goodness. So, to me? It was just fine. I didn’t want to spit it out or something. Others might find the taste repulsive, but in this case I don’t really think so.
