Picture this: two brilliant surgeons, Milk and Curd, performing their magic in the operating room. At first glance, you might think they're identical since they share the same raw material. But Dr. Curd, with her dahi culture starter, works her surgical miracles, turning milk into something entirely different. Imagine, if it weren't that different, we'd be sipping milk when our tummies rebelled—now that wouldn't be a bellyful of laughs! Now, let's get to the bread of the matter. Here comes Dr. Sourdough, a masterful surgeon, taking the raw grains and conducting a mind-blowing metamorphosis. It's like the dahi of the bread world. Just like dahi is to milk, sourdough is to bread—a magical, surgical journey with deliciously digestible results.
