Thank you, SourdoLady
The sourdough starter recipe provided by SourdoLady worked wonderfully. Having had some less than satisfying results with previous sourdough attempts, I was unsure of what to expect with this starter. Since first mixing it up a couple of weeks ago, it has been bubbling happily and smelling deliciously tangy. Since orange juice was on hand, I used that instead of pineapple juice. It sounded peculiar when I first read it, but I'm happy to report that it proved itself (pun intended) this weekend.
