Here's a tip to save that starter and take it with you or store it for another day when you need a break or don't want to throw it away.
This comes from a dedicated group of Austrian Ladies who travel a lot and bake bread.
Mix enough flour with the starter to form a stiff dough. Tear up into tiny pieces and squish between your thumb and finger to form thin small chips, let air dry, seal in glass jar or ziplocks. Send on holiday in a dark cool place. When needed add water to soak overnight and then feed to continue a new starter.
Once started, it never has to stop....happy baking! €:) Mini Oven
