We have successfully kept a sourdough alive for almost three months and we are pleased with the bread it produces. However, one great mystery remains. How do we keep the sourdough alive long term within the same jar?
The way we keep our sourdough alive currently is to take 113g of the sourdough, mix it with 340g of flour and 220g of water. This new sourdough then grows for 3 to 5 days before we repeat the procedure.
