Today's sour-dough rye bread looks like I'm starting to learn the basics. Thanks for the person who mentioned about letting it rise for a night. Seems like allowing it more time helps a lot. Yesterday morning I mixed some of the starter with warm water and added a cup of flour, then letting it sit for the day. I added more flour and made it to a bread before going to bed. Today in the morning I baked it. Also, I've learnt to better manage the oven temperature.
