over proofed my Tartine levain
I have baked the Tartine Country recipe twice now with good results. My levain usually takes 18-24 hours to float. I planned for the same time but instead it was ready at 12 am & I didn't want to start it then. I waited until 7 this morning &then it didn't float. I got the book at the library & since I made it twice without problems I neglected to write down what to to if this happens. I added yeast to the water & am trying to see what will turn out. If anyone has the correct fix I'd appreciate it.
