Has anyone ever seen kosher sourdough starter? I contacted King Arthur Flour- as suggested on an old thread here- and none of their starters are certified. I know that I can make it on my own, but I wanted to see if I can save time.
If you are ever anywhere near Riverdale, my wife and I have a 4yr old sour dough starter, originally born and bred in the UK and transplanted here two years back. We have a dozen or so mason jars around the kitchen...plenty to go around.
starters refreshed constantly with fresh flour and water and most is thrown out (or used to make pancakes.) So it pretty much maintains the same flavor profile for as long as you feed it. Unless you change flour and hydration.
