Dads Famous Orange Chocolate Chip Muffins

This here is one of my dads specialties. He doesn't cook a lot of things, but the stuff he does make is just unreal. He would bake these on Saturday mornings, I used to love waking up and smelling them. It was one of the few things that could get me up before cartoons started. The secret ingredient in these muffins is sour dough starter. Seriously. I didn't know it till I asked him for the recipe a couple weeks ago, you can't taste it at all. But it adds something to them, they just aren't the same without it. I actually haven't been able to make them myself since I haven't gotten my hands on any starter, but I figured I would share them anyhow.
