You can use both fed and unfed starter for bread. It will be a bit slower to start for the first rise but will be normal by second rise.So, I took my starter out of the fridge and let it warm up in front of the wood stove. Stirred it really well and then took 12 oz out to discard (it was really runny), then fed the starter with 1/1 flour and water.
So, Ron, are you saying I could have used the discard to raise the bread? I did't think it had enough oomph to get the job done. I'm having temp issues this time of year, so needed to feed starter but needed to get kitchen up to a reasonable temp (40*) this morning. When I separated the discard, we were up to about 75 and after warm water to the dough we were at like 78* for the dough. Temp in the kitchen eventually rose to 85* and then started to cool.
I'm still learning to manage temp with a wood stove.
Using yeast if fine though--changes the flavor profile a bit so it will be a bit less sour. Oh and the crumb will have a different texture. It is all tasty!
