Amber's Kitchen Sourdough Sandwich Bread

20 oz  sourdough starter (about 2.5 cups)
12 oz  warm water (about 1 cup)
4 Tb oil
2 tsp salt
6.5 cups flour (hold back about .5 cups to see if the dough needs it.)

In a Bosch mixer:
Combine all ingredients, adding the flour gradually.  Mix on level one and then switch to level two after a few minutes.  Mix for 10-15 minutes.  Flour, or oil, your hands and pull dough out of mixer.  Pinch the bread in half and form one loaf at a time in your lands and then place in 9x5 bread pan.  Let rise for 3-4 hours, depending on temperature.  Heat oven to 350 degrees and bake for 45 minutes.  Dump loafs out and let them cool on a rack.  For easier cutting, let bread cool, bag it up and slice it the following day.
