I understand completely! Tradition, tradition! Tradition!
No, I cut the brownies into squares, rather smaller than I usually would, because people at pot lucks generally like to have little bits of lots of things to try a whole variety. This involved first cutting the round brownie into a square, ‘wasting’ rather sizeable crescents (sort of, don’t know what to call those shapes, arcs on one side, flat on the other, thick in the middle tapering down at the end?)
Not that they went to waste.
