been making my own bread for a while now and wanted to give sourbread a go, i know how to make a starter but it's the long term care of it that i'm not sure about.
i intend to keep it in a wide neck glass jar (kilner jar or similar) but can it be kept with the lid sealed? i know when it starts it's life it needs to be loosly covered to get the natural yeast out of the air but after a week or so is this still the case?
cheers for any advice
