I got some tapiocas at home, I can make some experiment with that :-) I actually dont eat a lot of bread since my Asian tummy always craves for steamed rice, but I've been wanting to learn about sourdough to have some fresh baked bread at home since my partner loves bread.

Thank you for kind words Joanna. I really just wanted to share my experience and I want people to learn from my mistakes if they want to remake the recipe :-)
