Apologies in advance if this is a stupid question, or if it doesn't sound coherent, but: Is it possible to buy sourdough yeast, ready to use?
You can easily find "active dry yeast" for sale in supermarkets. I realize this regular bread yeast is a different variety from your typical sourdough yeast.
But can the sourdough type of yeast (I guess it is referred to as "wild yeast"?) be packaged in a way that you can just add it to your dough whenever you feel like baking, and not have to maintain a starter in a special container, with all the fussy feeding rituals, and worries about its health and environmental conditions, etc.? ... I imagine taking care of the starter must be half the fun, but people are always trying to make a buck by selling you convenience, so I wonder if you can buy little packets of "active dry sourdough yeast".
Or does wild yeast have some characteristic that makes it impossible to package it up neatly for sale? Or is there some other reason I haven't seen this product, even on the internet? ... Or do I just need to open my eyes, and I will see it in every market?
