@chris It was supposed to be 200 °C for 40 minutes.
I have a feeling something might be wrong with my oven because that's whats I've always done (https://intahnet.co.uk/deck/@mhamzahkhan/112113763731112658), and it's never been an issue, but this week I accidentally burnt two things, (First a store bought frozen pizza earlier this week, and now this sour dough loaf).
I feel like it might be getting hotter than I want it to?
