For a long time I have thought about making sourdough bread. Finally I created a starter on Sunday - one cup flour and one cup warm water. Mix well in a plastic container (metal including metal spoons can affect the mix) and leave in a warm place for a few days, feeding it with some flour and water each day. If it all works and picks up the yeast in the air, bubbles will appear and it will have a fermented smell.
It's looking pretty good so I am hoping to be able to make some bread soon.
I have been making bread for a while, by hand and with the breadmaker, so this will make a nice change.
