Tried making sponge based bread, but not pleased with the result. I've made bread all my life, but just my grandma's dump method. Soaking grains, then adding raised yeast, flour and molasses. My son's housemate made a wonderful sponge bread, letting it sit all day, before making a firm loaf. Can't seem to get the amounts of flour/ water / yeast, to get that special consistency. Any help out there?
