I have a sourdough starter that's a week old.
I have been feeding it every 12 hours, without discarding any.
I fed it this morning and 2 hours later, tried to make a loaf using the San Francisco Sourdough recipe from this website.
It hasn't risen after 4 hours.
I noticed 2 things about the recipe. #1, it never said "knead the dough", so I didn't. I just did exactly what the recipe says.
and #2, it calls for Buttermilk, but never said when to add it- so again- I didn't.
