Who knew? I took my mama’s Chocolate Sheath Cake recipe and switched the buttermilk up with sourdough starter and voilà ~ it worked. Which leads me to believe just about any recipe that uses buttermilk can be interchanged with sourdough starter. Maybe not all recipes…but cakes and breads, etc. (So far I’ve had wonderful success with my buttermilk biscuits and pancakes!) And taste-wise, I couldn’t tell any difference. Sourdough Chocolate Sheath Cake is awesome!!! This is great news for those of us who struggle over throwing away extra starter at every feeding!
