Verdict: our oven fucking sucks. It cooks at like 25-75 degrees hotter than what we set it at. Tried to compensate for this, but still ran too hot. Outside burnt, inside raw. Trying to throw some slices in the toaster oven, which works better but is too small to do baking in, but don't know how salvageable this loaf will be.
We ate a slice of the heel yesterday, and it was alright, needed a bit more spice, but if it is fixable in the toaster oven, some cinnamon sugar and butter will do it good.
Next time, we need to make more adjustments.
