Starter suddenly smells offensive
My starter ( about 2 years old if not more, generally performing well since I learnt to feed it sufficiently) has suddenly developed a really nasty smell. I was building it back up after returning from a 1 week holiday during which it was in the fridge. It was getting there with daily feeds , but over the last 2 days a smell has developed, I can only compare it to meat that has gone off. This was preceded by the texture turning gloopy and sticky. Prior to this it was getting back to the nice, aerated texture I look for. I’m wondering if this is a goner and I need to start again from scratch. Any advice welcome.
