yes, i'm starting from scratch... just four and water.... i just started another batch with flour, water and grapes... grapes naturally has a specific yeast organism on its skin. i like experimenting.
by washing, you mean dumping half of it and adding more water and flour?
well, i'll give my first batch 12 more hours... if it still smell questionable, i'll dump it although it looks great so far (bubbles and everything).
