I'm on day five on my starter - last night was the first day that emptied out most of the starter and refreshed it with more water and flour. Apparently my starter doesn't like it because it hasn't really bubbled up much, increased in volume, etc. It does smell rather stinky - in a good way - so I'm happy with that. I guess I just keep going, removing most of the starter, refreshing, etc?
I was also wondering if someone could explain to me why you take out most of the starter just to feed it more again? I'm working with the sourdough starter that's on the home page and this is my first attempt at sourdough bread. Is it just to make sure your starter doesn't overlow?
Any help / insight would be greatly appreciated.
