What is this yellow puddle in my starter?
My wild yeast starter has been going very well for a couple of weeks now. I have used it to make breads, cakes, and pancakes. I usually keep one cup in the fridge and feed it a couple times during the week then use it for baking at the weekend. I got it out today and was ready to make a sponge. But I saw some yellow color "puddles" in my starter (stored in a lidded plastic container). I scooped out the surface and brought the starter to room temperature. I was about to feed it an hour later, to my surprise, some of that yellow liquid had return. I have never seen such development in my starter. Is that normal? Here's a picture of it.
