Hi Walter! Unfortunately, that poor biga has reached the end of its life. For a biga, we tend to make sure to bake it within an 18-hour window. You want to bake with it right at the peak of ripeness, and we've found anytime after 18 hours is past its ripe stage. Sorry about that. But thanks so much for reaching out, and we hope you give it ago again. Happy baking!
