My father's a Chef. We made this the other day and it was great. I asked for measurements (sense he doesn't measure, all he does is pour in) and he gave to me. Hope you guys like. If your wondering what "spread caramel within 1" from the edge. Spread to within 1", means you want to leave a plain one inch border around the edges. Also, How did we cut the squares so perfectly? All we used was a sharp knife (that we dipped and wiped dry, every time) in hot water. Hope this helps, if you have any questions, let me know... Enjoy!!!
