Add the sourdough starter, warm milk, butter, egg, salt, and sugar to the pan of a bread machine ( or follow the instructions for your particular machine).
Add the flour and yeast. Place in bread machine and set for dough cycle.
When the machine beeps, check the height of the dough "without opening the lid". If it has not risen, allow to continue to rise for an additional 30 minutes.
Place dough on a lightly floured work surface and knead a few time to release the air pockets and form into an oval ball. Allow to rest for 10 minutes.
Roll the dough out into a 15 X 18 rectangle.
For the Filling:
Brush with butter.
Mix the sugar and cinnamon together in a small bowl, and sprinkle over the butter.
Sprinkle chopped pecans over the dough.
Starting with the long end of the rectangle, roll the dough into a log.
Cut (12) 1 1/2" slices from the cinnamon roll log.
Place in a buttered/sprayed 9 X 13 baking pan.
Cover and allow to rise for 45 - 60 minutes, or until doubled.
Bake in a preheated 350 degree oven for 20 - 25 minutes. Remove from oven and allow to cool for 15 minutes or so while you make the orange syrup.
For the Orange Syrup:
Pour orange juice, sugar, honey, and lemon juice into a small sauce pan.
Bring to a boil, then reduce heat and simmer for 20 minutes.
Pour the syrup over the cinnamon rolls in the pan. Allow to cool before serving, the syrup is extremely hot!
I poured about half of the syrup on the cinnamon rolls, and saved the remaining syrup to pour over when they are served.
