At the Adelaide Central Market there are 2-3 bread/bakery stalls. One of these had a wholemeal rye round loaf that smelled and tasted fantastic! I took a loaf when visiting friends living outside of Bathurst. When I opened the boot of my car their dog tried to jump in and they asked if I had a cake in there. Nope, just a loaf of bread, real bread. Unfortunately, that bakery must have closed or changed hands and that bread is just a memory now.

So just before the loaf of dough goes into the oven the top of the dough is quickly slashed. Dough can rise without exploding. That is why real crust, firm and chewy, looks like this:
