Not really concrete, more like .... library paste Flour and water, and a few million healthy bacteria ... a very healthy library paste. This is why I always keep a layer of wax paper between the container and the lid.
I am using 1/4 cup rye, 1/2 cup WW, and 1/2 cup water. This mixture has been working wonderfully for me--rising more than twice it's size. Tomorrow it will be a week old and I am going to try and bake with it. I know I read somewhere to switch over to white,(and the only white I have is bleached) but I can't find out why we should switch. Is it for the gluten content? My family prefers WW bread, so I was just wondering.ORChick said:Not imperitive, no. For that matter you don't even really need to switch over at all, unless it is important to you to have snowy white bread. Although in the end a loaf of bread will only have a small fraction that was the starter; a rye starter in a white loaf will hardly be noticeable. What do you have - bleached white, whole wheat? If you are concerned about the outcome you can always divide your baby starter, and just switch over with half of it, and see what happens.
