Since the unfortunate demise of my starter and the jar of leftovers I have been busy making new ones. SourdoLady's pineapple juice one and the yogurt one I started out with originally. SourdoLady, the pineapple one started out well but hasn't done much of anything since I changed to ap flour and water. I have stirred like crazy, added a spoonful of rye, even tried the apple cider vinegar. I am now to day 11 and there are bubbles on the surface but no sign of rising. What do you think - should I keep on repeating day 4 or toss it and start again? I really want it to work.
