And the longer you can keep it going the better! Mine is only a few months old right now. I go through phases of using it, then letting it sit too long, throwing it out and starting a new one to use for awhile. I think the longest I've kept one going is about three years.
Here's a starter....
1-1/2 cups lukewarm milk
1 package active dry yeast
1 tbls sugar (more or less to taste, or use honey)
2 cups unbleached white flour
1/4 cup water
1. To prepare the starter, place the milk in a mixing bowl. (I use stoneware - never metal)
2. Sprinkle the yeast over the milk.
3. Whisk in the sugar and 1-1/2 cups of the flour.
4. Cover with a clean towel and let sit at room temperature (72 to 76 degrees F.) for 72 hours (3 days).
5. After 72 hours, stir in the 1/4 cup water and whisk in the remaining 1/2 cup flour.
6. Cover again and let sit at room temperature for 2 hours; the mixture should be bubbly and have a sour, tangy aroma and taste.
7. Remove the amount of starter the recipe calls for and set aside.
8. Transfer the remaining starter to a sterile' glass jar or crock and replenish it by mixing in 1 cup water or milk and 1 cup flour. Cover tightly and store in the refrigerator. Each time you use it for a recipe add back the 1 cup flour and 1 cup liquid.
SourDough Pancakes:
The night before you serve them, mix one cup starter, two cups flour and two cups milk - let sit at room temp overnight.
In the morning add 2 eggs, 1/4 cup sugar, 2 tsp baking powder, 1 tsp salt.
Make like regular pancakes and serve with real maple syrup and you will the HERO!
I also make sourdough biscuits, bread, you name it!
For the chicken fried steaks - I used minute steaks, dipped them in starter then dredged them in seasoned flour and fried them till golden in a little butter and olive oil. Make gravy from the drippings and serve with mashed potatos and your favorite green veggie and salad - another meal that will make you a hero
