Somewhere along the way I got the idea that I should be able to make sourdough cookies. I thought about it for a week or two and decided to look for a recipe and found this one . I didn't need to make a starter as I already had one so I just followed the reciepe like it is written for making the dough. I let the dough sit for a few hours after I had it mixed up to let the yeast and bacteria get active then I put it in the fridge over night. They were cooked for 15 minutes at 350°F. The critics here gave the results an A+. I'm thinking the above recipe is a good starting point for all kinds of different cookies.
