The best way to slice cinnamon rolls
While you can certainly use a knife to slice a log of cinnamon roll dough into individual rolls, I find that it can result in squashed and lopsided rolls if your knife isn’t quite sharp enough.
My favorite way to slice cinnamon rolls is with unscented dental floss or clean thread. Measure out about 12-15 inches, slide it under your dough so that it’s centered, wrap it around the top and pull tight in one quick motion. The floss/thread should cut cleanly and easily right through the dough. Repeat at even intervals.
