The other reply is correct that I used a knife to cut my final rectangle of a dough into 6 pieces. Like I said, I very rarely bake, so I don't actually own any biscuit cutters. Plus, part of the exercise today was to get me to let go of the block if have in my head about baking being fussy, so this was a (somewhat) intentional rustic approach to the dish. After cutting the dough into individual pieces, they all fit into the bottom of that square pan, with a couple centimeters to spare between most of them. I figured that if they expanded against one another, that would actually help push the rise further vertically, so I wasn't bothered by merging if it occurred. However, it turned out that the majority grew straight up rather than out, and most of them were fully freestanding when done baking.
