Sourdough Pancakes

These have become my favorite pancakes. I love these with buttermilk syrup. The only thing is you have to remember to start them the night before.

Sourdough Pancakes
1 large egg - lightly beaten
1/2 tsp. salt
1 tsp. sugar
2 TBSP water
1 tsp. baking soda
2 tsps. butter - melted

Starter:
2 1/2 cups all-purpose flour
1 1/2 tsps. yeast
2 cups milk

In a bowl whisk together 1 1/2 cups of the flour, yeast and 1 cup of the milk. Let mixture stand in a warm place, covered loosely, overnight.
Whisk 1/2 cup milk into the starter. Dissolve baking soda in 2 TBSP. hot water. Add to the starter, remaining flour, egg, salt, sugar, baking soda mixture, butter, and remaining 1/2 cup of milk; whisk until the mixture is combined well. Heat and grease griddle, then cook pancakes.
