Lisa, this is my favourite starter. It is a pure starter, made from just rye flour and water. Nothing else. Once you get it going and it is easy to keep. YOu just have to feed it occasionally.

Once you get your starter active, you use it to make a biga or a levain and that is what you add to the French baguette recipe rather than yeast. For the Biga, I just add 2 ounces of starter to 1 1/2 cups of flour and a cup of water and let it develop overnight.

This starter is begun with rye flour because rye just LOVES to ferment and is an easier starter to get going than a wheat starter. When I first made it, it had a bubble or two within a couple hours.

The procedure is to start it with rye flour, then transform it by changing what you feed it. The original rye will dilute to nothing over time and you'll end up with a white flour (or whatever other grain you choose, it could be whole wheat or pumpermickel, or you could leave it as a rye starter) and water based starter, but it had the advantage of beginning it's life from highly fermentable rye flour.

Start it with organic rye flour and spring water. Once you have it going well you can switch to all-purpose white (or other) flour as you choose. The use of spring water is recommended for maintenance, however, as tap water may contain elements (such as chlorine) which may be detrimental to the health of your starter. I also recommend that you use a container that you can mark the volume levels of starter each time, so that you will know when it has doubled. Use a marking pen or tape or any other means to indicate on the container the starter levels each time you feed.

Phase 1 - Combine 2 oz organic rye flour (room temp) with 4 oz spring water in a clear container. The batter should be about the consistency of very thick pancake batter, add more water or flour if necessary. Cover & let it sit for 36 - 48 hours at 75 - 77 degrees (a little cooler is okay but over 80 you will incubate the wrong kind of bacteria and your culture will have an unpleasant bitter taste). You should start to see tiny bubbles forming after about 24 hours. By the time it has doubled, there will be a noticeable network of small bubbles throughout the batter & it will be foaming & bubbling on top. (If the batter has not doubled within 48 hours, feed with 2 oz water & 2 oz flour (add more of either if necessary for the consistency) and let it sit another 24 hours or until you see some definite activity.)

Phase 2 - Stir the culture down, notice how soupy it's become. The batter should have a noticeable sour smell & a mildly tangy taste at this point. Add 2 oz water & 2 oz flour and stir vigorously until well-combined. Let it sit for 12 hours. It should be showing a fair amount of activity at this point. You should see lots of foaming & bubbling through the sides as well as on the top. Don't be concerned if the culture deflates & loses volume. This means the yeast has exhausted its food supply, but it will continue to increase in acidity. Don't worry if your culture isn't dramatically active yet. As long as there is some noticeable activity going on and the mixture smells & tastes sour, you're on the right track.

Phase 3 - The culture should now have a pronounced, sour, fruity taste and smell, it should not taste musty or bitter (if it does, discard and start again, paying close attention to the temp of the culture at all times). Now you can start "transforming" it into a white (or other) flour based starter. Use 6 oz of the starter, add 3 oz water & 3 oz flour, stir vigorously. Let it sit for 12 hrs at 75 - 77 degrees F.

Refresh it again, setting up a maintenance level of 12 oz of starter. This will be your "mother" starter that you use to build the sourdough starters/sponges needed in individual recipes.

Each time you take part of the mother out to build a starter, you must refresh it with equal weights of flour and water to bring it back up to its maintenance level.

To maintain - Use 6 oz of the mother culture (discard the rest), add 3 oz water & 3 oz flour, stir vigorously, let it sit at room temp until doubled in volume.

A strong mother will double in 8-12 hours. If yours doesn't do that, let it continue to sit out until it has a nice tangy taste and smell; discard all but 6 oz and repeat this procedure. Repeat this procedure as many times as necessary until the mother doubles within 8-12 hrs. It may take several days. Don't get discouraged, it's worth the effort.

To use for recipes - Combine 1/2 c (5 oz) Mother from the refrigerator, add 3 oz flour and 2.5 oz warm water (85 - 90 degrees). The mixture will be stiffer than the mother. Let it sit, covered, until doubled in volume (if it doesn't do so go back to maintenance procedure). When the starter has doubled, it is ready to use in a recipe. Measure the amount needed and discard any that remains.

Thank you.
So, when I take the 5 oz out and make the biga, how do I turn that into bread?
Lisa

I use two onces to make the biga. Leave it to rise overnight and then add it to about 4 cups of floor, enough water to make a dough and about a tablespoon of salt. I usually let the mixture sit for 20 minutes to absorb the water before adding the salt. Then knead your dough and let it rise. One or two rises. Up to you. And then shape, rise and bake.

Exactly measurements when it comes to bread are really not important.

Until you are sure that your sourdough starter is really active, add about an 1/8 to 1/4 teaspoon of salt to your bread. This is very common in commercial bakeries to ensure consistency. (According to Amy's Bread)

Thanks again. I have printed these instructions out this time and will be starting the starter today.
I assume you mean add about 1/8 to 1/4 teaspoon of yeast in your second post, don't you? Just want to make sure.
Lisa

Lisa, yes, add the small amount of yeast when you are making the dough for the bread.
