Hello from Rome (Italy) and ... Yeast Water, Sourdough, WHAT ABOUT IT?!
I am new to this and I came to this forum thanks to a Friend who really made me curious about words like "sourdough", "yeast water" - by a rapid look to the awesome recipe (like this ) I found.
I don't have much experience in baking Bread - even if I come from a town known all over Italy for its wood-oven cooked bread  - but I have some experience with baking Pizza at home (getting this "natural yeast" from the local pizza-maker).
I would like to know more about this process which doesn't involve buying yeast, but just using the one naturally present in the flour, water, air?! Where can I start getting some information about it? This seems the right place to ask ... ;)
