Thanks NCB! :) Yes, I think I'm always going to have problems using my offset spatula with the 8 x 8 tin. Even if the tin were shallower, the spatula including handle is too long to fit within the walls properly. I might try seeing if I can bend the angle of the blade a bit more, something around 45 degrees, so that the handle is more vertical. Nope, you explained the process very well.\nI left it for about 15 minutes and then made the cuts. But I've got all pieces on 2 plates in the fridge now so tomorrow I'll melt the chocolate.\n\nI've made quite a few things that are slightly underbaked! Kind of annoying. I guess I should have cooked it for the full 45 minutes at least, perhaps even 50.\n\nI ended up with 33 larger pieces which is more than enough for me. But with an 8 x 8 tin and the dough cut into 2" x 1/2" rectangles, I think I should have had 64. And I did use a ruler sitting across the lips of the tin, but the problem was I couldn't actually get the ruler down inside the tin, so I eyeballed it and used my plastic dough scraper to score it. But my lines were wonky giving uneven sized sections. I can buy a half length ruler though, that would work better. Or maybe I need one of those metal dough cutters that have centimetre and inch markings on. Once I slowly and very carefully lifted it out of the tin (that was certainly a precarious moment for fear of it all falling apart!) I cut it again but I had to follow the uneven scoring that was still visible.\n\nNext time, I'll do what you do and completely leave the scoring until it's out of the tin so that I can slice right up against a ruler.\n\nAlso, before baking, the dough was getting very soft in the tin and made scoring and fork perforations more messy. I did chill it for 15 minutes before baking but probably should have also chilled for a few minutes before scoring and docking.\n\nYes a cake ring would be easier! I'll have to consider getting one. I look forward to hearing how your corn and rice flour combo is when you've made it. And, if the tin your sister gave you is dark, I guess you'll be wanting to bake for longer on a lower heat?
