Pineapple juice starter
I started my first sourdough starter about a year ago. I didn't want to order a starter from King Arthur I wanted to capture the wild yeast. So, I searched this sight and found the easiest starter possible using ground wheat berries and pineapple juice. It worked great and I now have a beautiful, mature starter, but it just doesn't seem to do well if I don't feed it with pineapple juice. I would really like to feed it with stuff like flour,sugar and water, but it refuses to double when I do. Any suggestions?
