I have a sourdough starter that I feed in the portion 1:2:2, to start a levito can I use my starter or is better to start a new one specific for the Panetone? Thanks, and sorry for talking in English, but my Spanish is terrible 
Gonzalo_Pardal Hi!
Try with your frock coat, I think the result will be good.
Enjoy!
Hi Josep. With my frock coat? Sorry didn’t get it
What do you mean with starting a new one? From scratch? If you already have the sordough you can just use it no?
Hi Gonzalo_Pardal & Albert_Vila_Calvo.
If you have enough use yours and if not create a new one.
