So I decided to make yeast water with it.
On the same day, a jar of marmalade was finished so I used it without washing it.

Now I am making preferment.

Playing with home-made yeast and dough. YEAST FREE BREAD BAKING. I'M ENJOYING BAKING WITH NO COMMERCIAL YEAST. Cultivating natural yeast from fresh fruits, dried fruits and etc.
ENJOY BAKING ! PLEASE BAKE AT YOUR OWN RISK
