What's the least and most amount of time required for a sponge (or starter)?
New to this of course. A youtube video by Dave of Dave's Killer Bread showed that he let his sponge or starter (can't remember which he called it and don't know if there's a difference) sit on his counter for about an hour before continuing to add flour and mix more/knead.
Some googling (haven't yet read my bread books!) showed lots of comments about people letting their starters sit for several hours.
Last week I made Dave's recipe and let it sit for only an hour and it came out fine. Tonight I'm doing a different version (an imitation recipe I found online of his more seedy breads which he doesn't share recipe-wise) and I'm making 4 loaves instead of 2. Any reason I should let it sit for longer than an hour before continuing to mix and adding the rest of the flour, etc?
