85% Hydration No-Water-Added SD Sweet Potato Milk Loaf

I've been developing this formula for weeks, and I was testing the possibility of adding more sweet potatoes into my loaves. I didn't plan to post it, but thanks to our brief discussion with Debra, I decided to post it.
Steamed sweet potatoes were used to make this loaf. They hold water really well, handling 85% hydration dough felt like handling 75% hydration regular tangzhong dough. You may say this is tangzhong on steroid.
