In a large bowl or mixer, add water, starter, eggs, honey, oil, and salt. Mix to combine.
Add 8 cups of flour and mix well. Add the rest of the flour one cup at a time, mixing or kneading until the dough is smooth and elastic. It should pass the window pane pest. (Where you stretch a small part of dough and you can see light through it, but it doesn't break.) If it doesn't pass, keep kneading. This may take 5-15 minutes.
Cover with a towel and let rise until double.
Dump out dough onto a lightly floured surface. Divide into four and create round loaves. Then roll to form a loaf and place in a greased loaf pan. Divide each round loaf into 12 buns if you're making buns and place 12 buns into a greased 9x13 inch pan.
Cover with plastic wrap and place in the fridge overnight for a long ferment. This helps develop that rich sourdough flavor and breaks down the grain to make it more digestible.
The next morning, remove the bread from the fridge and let sit on the counter until doubled. It may have doubled in the fridge. If so, you can bake it!
Preheat the oven to 375°F. Bake loaves for 30 - 35 minutes. Bake buns for 20 - 25 minutes. Remove from pans and cool completely on a wire rack. Enjoy!
