I put on my breadmaker to do some dough for rolls as usual. I forgot it was on so it got left beyond its finish time. When I took it out, it had obviously risen way too high so I "worked" it, pounding it down before shaping the rolls. But before I had finished, it changed texture and became a sticky mess even though I added flour. I managed to scrape it off my hands into rough round shapes and have left it to rise, but am I wasting my time? Is it going to be horrible? What went wrong??
