Teresa, when I use my sourdough starter I only use a couple of ounces to make a biga and the biga is left overnight to develop and in the morning it is added to the flour with additional water and salt. I don't measure the water because it varies every time depending on the flour, the weather, etc... I go by feel and whether I'm looking for a more hydrated dough or not. Depending on how active your starter is, I don't see a problem with using substantially less than one cup. Ann

I would suggest you give the starter another 4 days to a week to "age" a bit. Then first making sure you have enough to keep some back, take out what you need for your recipe about 3-4 hours after it has been fed. [You don't want to use all your starter in your recipe and have none left to keep in the frig - do you? Then you would have to start all over again.] Prepare your recipe just after the starter has expanded all it's going to expand. It will just go down hill from there. When you add the recipe ingredients to it, it will recognize the feast you are giving it and go to town on that. It is alive, you know? Teresa

Ginny, you will find all kinds of different advice. Here is how I use my starter. When I take it out of the fridge to feed it, I take 2 ounces of the discarded starter (60g) and mix it with 225g of flour and 225g of water. Stir well cover and leave to double. Once it is doubled, I add it to 1000g of flour , 680 to 750g of water, and 26/27g of salt. So based on when you want to make your bread. I would make the preferment now. It should have doubled in about eight hours. Then you can make your dough and put it in the fridge for an overnight longer fermentation. Bake tomorrow. Take the dough out of the fridge about 3 hours prior to shaping. It needs to come to room temperature and start to rise again. Then you can shape and proof and bake. If this is the first time you are using your starter, you might want to add a pinch of yeast just for insurance. Or just take your chances. ~Ann Here is a link that might be useful: Sourdough Bread This post was edited by ann_t on Fri, Nov 14, 14 at 16:51

Hi Nancyjane, There are a few sourdough bread bakers here (I'm not one of them). I bake bread but I don't like the taste of sourdough. Here's a link to a conversation by Ann_T, in case she doesn't chime in. Sourdough
