I have done it both ways. I use yeast when I am pressed for time. This also lessens the sour taste due to shorter fermentation. If I use a longer fermentation the more sour it tastes.hot stuff said:Is that how long it takes? I never made a pure sourdough loaf before but I started one last night and well it grew a little but it has a long way to go to be bakeable.
Are you fermenting at room temp or in fridge?
