Dough - Step 2
Instructions
Scald milk, add shortening, sugar, salt and potatoes. Add half the flour before adding eggs and yeast mixture. This will help cool the mixture so the scalded milk doesn't kill the yeast. Mix until combined in a mixer. Add flour until a soft consistency - not too sticky. Cover and let rise until double its original size (about 1 hour).
The trick to these cinnamon rolls is in the soft dough. To keep the dough soft mix the flour in just until the right consistency, don't over mix. As soon as the dough is the right consistency -- starting to pull away from the sides -- I turn off my mixer. Also, don't add too much flour. I err on the side of the dough being a little sticky. I can always add more flour at the roll-out step. For the mashed potatoes - I have made instant potatoes frequently. I add the extra water, and potato flakes to the scalded milk before adding the other ingredients. It's important to cool the milk down to 120* before adding the yeast.
