From wheat flour or rye flour with yeast???
Do you know we can make sour dough bread from apple cider??
Long, long time ago, that's how to make bread with no instant yeast.
I made this apple cider from apple by myself. Just small amount, one small jum jar of it.
Then made sour dough polish with flour and the apple cider!
Strong proofing, non instant yeast, non suger.
That's real non additives at all!
I made Ciabatta with apple cider sour dough!
Simple home made bread!!!!
