This might seem like a stupid question... however, I always see people making horizontal slices through the onion and I can't seem to understand it. I have tried it with and without the slices and I can not really tell the difference in the finished product. The horizontal slices actually make it harder to keep everything together for me. I am wondering if anyone can shed some light on this subject for me other than "because that is how it is done" or "that's how we have always done it". I really want to understand the reasoning for the way we do things as we do them.
