suddenly stopped rising
I've been making relatively successful sourdough for a few years with a self-made starter. I recently went on holiday for a few weeks and had someone feed my starter once while away (something I've done many times before).
The first loaf I made after returning was wonderful - one of the best rises I've ever had - properly huge and fluffy.
I've made two loaves since and now there seems to be no oven rise at all (and noticeably less rise in first and second proves, which I do 11 hours first prove and 12 hours in fridge second).
I'm generally pretty rough and ready with my starter (feeding often enough but not by measure and with mostly white and a dash of rye flour) and it's always been up to it. Never have I not had any over rise at all.
Many thanks in advance.
