Hi! I am making a 100% sour rye and I wanted some advice on my preferment, the recipe says to let the per-ferment ferment for 18 hours.
My parent's house is warm and this is what it looks like after 9 hours, what are some signs of a ready preferment?
When do I know how to use it?
what does it smell like?
Does the recipe you're following give a temperature for the preferment? And what is the temperature of where you are at the moment?
I think it can go for longer to make a really ripe starter but another 9 hours I'm not so sure. Explain the preferment build.
