Purple sweet potato sourdough
It's been a long time since I tried something weird.
Guys this method worked!
When using a large amount of sweet potatoes in one loaf(1/3+ of dough weight)
Instead of kneading the mash sweet potatoes in the dough(which change the whole structure of the dough if you're using that much)
Or making 2 doughs and laminate together for the swirl
Pick one of your simple recipe, treat it like a puff pastry, encase the sweet potato in the dough and do your 3-4 coil folds that way, and you'll get the swirl, the flavor the spring all in one package!
