Slack new starter; no rise; smells very pleasantly sour
I'm starting to feel like a pest. :(
My starter is now 13 days old. It smells (and tastes) wonderful. The texture seems a bit odd, and it is not growing. It feels like a very slack dough. When I stir it periodically throughout the day, it develops into a domed heap in the middle of my jar, then flattens out.
I'm feeding it every 12 hours with this method:
reserve 1/4 cup
add back in 1/4 water
add back in 3/8 cup flour (KA white unbleached bread)
I did add in 3/8 cup KA WW about 5 days ago, which spurred a slight growth spurt (25%?)
Is it still starving? Should I increase the WW? Do a mixture of WW/WUB for a while?
