A Biga & A Sourdough Starter - Baking & Pastry Week 21

Posted Mar 15 2010 7:15pm


A Sour Story

This week I'm wrapping up my exploration of bigas and moving on to sourdoughs. I'm going to make a couple of different types of sours, starting with one that is light colored and mild flavored like one made from bread flour.  The second will be stronger in flavor more like a rye flour. The final sour will be a whole grain style made with a stronger alternative flour, i..e. buckwheat, amaranth, teff, etc.

This first sour is mild and slightly colored and flavored with corn flour or an extra fine ground corn meal. It will take five days before your sour is ready to be made into a loaf of bread. When you measure out your flours to begin the starter, go ahead and measure out the rest of the flours for each feeding. Then your feeding process will be quick and easy.

If you are having trouble getting your culture started, you can add a grape, apple slice, onion or potato pieces. You can even use the water from boiling potatoes for your water in the recipe. I like using a mixture of flours in my sourdough starters, as I think you get a more vibrant culture. 

Once your sourdough culture has been established, you will need to feed it again once the dough has risen and then recedes from it's previous feeding.

Enjoy!

What's Going On?

I was a very lucky woman and received a copy of the Culinary Institute of America's Baking & Pastry book along with their culinary dvd's from my family for my birthday and our anniversary. After watching all the DVDs, I decided to work my way through the CIA's Baking and Pastry book - of course making it gluten free. There were so many skills that I wanted to develop and work on. I hope you will be interested in sharing my journey with me.
