Sweet Potato + Stock Sourdough

I'm baking a sourdough that has leftover sweet potato mixed into the dough and leftover vegetable stock. Last week I used leftover pumpkin puree and it was excellent.
UPDATE: Baking with bean and broccoli stock is too strange. It smells like cabbages when I make toast. Next time I will only use the sweet potato or the pumpkin in the dough.
