Sour Dough Starter from Scratch
1/2 cup plain yogurt
1/2 cup milk ( skim, regular or buttermilk) 1/2 cup unbleached flour
1. Mix the milk and yogurt together in a glass or pottery container (Do not use metal).
2. Place lid on it, but don't seal it (sealed starters have been known to explode).
3. Put mixture in a warm place (80 to 90 degrees) for about 24 hours.
4. The yogurt and milk will separate forming a large curd, when adding the flour just stir it all back together.
5. Add the flour stir, and put back in warm place for 3 to 5 days; stirring daily.
6. It will bubble and have the odor of fermentation it is ready to use.
7. Remember the starter is a living thing and needs to be fed and fed frequently when an infant.
8. I feed the "infant" weekly by placing it on the counter for several hours and allowing it to come to room temperature.
9. Then remove 1/2 cup starter, discarding the remainder.
10. Feed the 1/2 cup with equal amounts of milk (buttermilk will produce a stronger sour taste) and unbleached flour; i.e. 1 cup flour and 1 cup milk plus 1/2 cup of starter.
11. If you would like, you can feed the starter with 1/3 cup dry milk powder and 2/3 cup bottled water in place of the 1 cup milk.
I have tried this and was very simple very easy always remember to feed it or fridge it and
it will last many years... I do want to add you will need to feed and discard at least one week before it will work without yeast.. and I did use plain greek yogurt as it was the only plain one at the store just then.
