A few more points to ponder in the continuing saga of cinnamon rolls:
The addition of mashed potato to the sweet dough adds moistness, a light
texture, and considerably improves the softness and the keeping qualities
of the rolls.
Including the raisins in the dough rather than placing them on top of the
rolled-out dough, makes for softer raisins that are better incorporated in
the roll, less likely to fall out or to dry out/burn in the oven.
Slice the rolls with dental floss, as others have mentioned, to help
maintain the shape of the roll.
Happy Baking!
