I didn't have any parchment paper, so I used foil, which really shouldn't have made that much of a difference. I think that if I make it again I will put it in a dish set in the cooker, so that it doesn't directly touch the sides. Interestingly, the bread all along the back of the ceramic pot burned the worst, and the bottom not quite as badly, and it didn't burn on the ones in the front. So yup, there's definitely hot spots! (Since the element is under the pot, I would have thought it would have been the bottom that burned. Huh.)
Perhaps cutting the cooking time down would help? I've always heard that the difference between high and low on a slow cooker was just the amount of time it takes to get to the "cruising" temp, so putting it on low probably wouldn't make a difference. Mine also has a "warm" setting, so I wonder if firing it up to the usual cooking temp and then dropping it to warm would cook it through without burning it?
There was enough unburnt that I ate way too much, anyhow, and it was good! Thanks for sharing it!
