Step 1: Supplies
Step 2: Slicing
Lift the end of your dough (These photos are from my Heart Cinnamon Rolls) and slide the thread under the dough.
When you have the thread where you'd like to make the cut, cross the two ends over the top of the dough and pull them in opposite direction. You now have a perfectly cut slice of dough.
Using the thread gives you nice clean slices. I've found that using a knife makes a mess. The dough sticks to the knife unless you have it covered with oil, which then in turn gets on the dough.
Cutting dough this way is so easy. It's great for kids if they want to lend a hand in the kitchen.
