Here's a recipe I got off of the internet a couple of months ago and it works very well. I've also included a sourdough pancake recipe that I've made for years that's just delicious.
Blend a cup of warm water and a cup of flour, and pour it into the jar. Add about a teaspoon of yeast.
· Every 24 Hours, Feed the Starter. You should keep the starter in a warm place; 70-80 degrees Farenheit is perfect. This allows the yeast to grow rapidly. Temperatures hotter than 100 degrees or so will kill it. To feed the starter: (A) throw away half of it and then (B) add a half-cup of flour and a half-cup of water. Do this every 24 hours.
Within three or four days (it can take longer, a week or more, and it can happen more quickly) you should start getting lots of bubbles throughought, and a pleasant sour or beery smell. The starter may start to puff up, too. This is good. When your starter develops a bubbly froth, it is done.
Keep the starter in your fridge, with a lid on it. Allow a little breathing space in the lid. If you're using a mayo or pickle jar, punch a hole in the lid with a nail. Once the starter is chilled, it needs to be fed only once a week. Realistically, you can get away with less; it's important to remember that your starter is a colony of life-forms that are almost impossible to kill (except with extreme heat). Even starving them is difficult.
Care and Feeding: Hooch
Aside from weekly feeding, the only other thing you need to worry about is hooch. Hooch is a layer of watery liquid (often dark) that contains alchohol. It smells a bit like beer, because it is a bit like beer - but don't drink it! Hooch builds up in your starter, especially in the fridge. Just pour it off or stir it back in. It doesn't hurt anything. If your starter is looking dry, stir it back in. If your starter is plenty wet, pour it off. Just remember that hooch is nothing to worry about!
