Leftovers

You will have to make sourdough every second day to keep your starter healthy, although it can be frozen if you want a rest. Any discarded starter can be turned into a tasty savoury pancake, according to Sandor Katz, author of The Art Of Fermentation. Fresh sourdough is the best, but a good sourdough loaf will keep for 2-3 days in an airtight container.
