Fermentation Basics – Keeping Sourdough Alive

Loafin’ around

Sourdough is really bread that has been leavened with starter (natural yeast), rather than with commercial yeast.  It is delicious, has some terroir and if you like sour dough (or not!) you can control the sourness by how often you feed it.  I use a desem starter.  The desem culture originated in Belgium, as the Belgian answer to the French pain au levain (aka French not-so-sourdough).  It is meant to be fed whole wheat flour and eventually, to make whole wheat bread.

I’ve had mine for almost 3 years now, though I did accidentally use it all up one time.  I don’t count that because I’d given some to a friend beforehand, and she gave some back to me after his death, so I like to think of that as my culture going off to get a little culture, then coming back home.

Personally, my favorite way to start starter is to get some from a friend.  I love that the bread you bake will have a sense of history and community, and a little bit of the character of your friend’s home, too.  It’s really easy to make your own if you don’t have a friend with starter.  Here’s a great tutorial from Serious Eats.  If you live in Philly, I’m happy to share mine since I ALWAYS have extra.

The key to sourdough is regular feedings.  I think of mine as a pet so I feel bad when I don’t feed him.  Also, since he’s Belgian, I call him Hercule. Get it?!

I use my iPhone reminders feature for all of my ferments, otherwise people (okay, ferments) die.  And it feels horrible, like when you kill a plant you grew from seed.  An established starter should be fed at least weekly, and refrigerated between feedings.  If you keep your starter on the counter, it should be fed daily. In the summer heat, I could stand to feed him twice a day, but he generally gets by on one.  The only reason to keep your starter out  is to have it ready to use.  If you’re not baking bread everyday, by all means, keep it in the fridge except for those essential weekly feedings.

Feeding process:

Take a small amount of starter.  I like to go by weight, but you can also do volume, no problem.  I take 3 oz. (you could do a quarter cup, say) of starter, add 3 oz. of whole wheat flour and 3 oz. of water.  I like my starter a tad wet, but if it gets too wet or too dry, you can add a small amount of extra flour or water to get it back to your preferred wetness.  Obviously if you’re about to bake a big loaf of bread or make multiple pizza doughs, you’ll want to reserve a larger amount of starter to feed so you end up with enough finished product for your recipe.

That’s it! Let it sit at room temperature or slightly warmer for 12-24 hours and then do the above process all over again (or stick it in the fridge).  There are many ways to use that extra starter that inevitably starts to pile up.  Here’s a link to my favorite way to use that extra starter so you don’t need to trash it.  Extra starter will store fine in the fridge for a week or more, but it does get increasingly sour the longer it’s there.

If you get tired of feeding your starter, are going on vacation or just won’t be using it, you can store your starter in the fridge for a week with no problem.  Just feed it  at 12 hour intervals once you’re back and it will be back to normal and ready to use!

Once you have a good amount of starter bubbling, you can make delicious things, like bread!

    Hi! I just read Michael Pollan’s Cooked and I’m now totally obsessed with sourdough starter and with the idea of pickling veggies. Could we maybe get together and talk starter sometime?

    I see that you’re going to be at Circle of Hope this coming Thursday evening — I live in the neighborhood, and I’ll try to stop by and hear about your adventures in fermentation.

    Cheers,
    Nadine
