Keeping sourdough long term in a jar
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.
We would like to keep the sourdough in an old glass jar (sealed lid) permanently and simply feed it without removing it every time. Does anyone know how this might be achieved? I have not found any real solutions online so far...
Many thanks for taking time out to read this.
