How do you know when a homemade sourdough starter is ready to roll? I made the sourdough starter briefly discussed in the intro to Classic Sourdoughs by Ed Wood. It was 1 1/2 c. flour and 1 c. water sitting out at room temperature. After about 2 1/2 days (I stirred it down twice a day), it was about like bubbly muffin batter so I fed it with 1 cup flour and 1 cup water. Then it bubbled up to about twice the volume. In the book he says it is ready when you have one to two inches of foam on the top. Now I'm thinking beer foam or something like that. Instead I have a bubbly muffin batter. It is definitely alive in some sense as you can kind of see things moving if you stare at it long enough. Am I ready? Also, the book's recipes either specify a liquid culture or a sponge culture. It doesn't say which type I made but am I right to assume it is a sponge culture? You can kind of pour it (I needed to divide it because it was bubbling over the container) but it isn't as liquid as some sourdough starters I've had in the past. Thanks for any help you can give me!
