Stiff starter is slow to rise
I've been working with Leader's stiff levain for a few months now and it has always ripened (doubled in volume) within 8-12 hours after feeding. My usual routine has me feeding and baking 2x per week. However, after a few days in the fridge, it seems to be taking its time today. It has risen about 1.5x after 24 hrs this time. I'm thinking that I may skip baking with it and try a few days of feeding to see if it perks up. Does anyone have any ideas as to what else I can try? Thanks.
