I made a sourdough but included 2 bananas, about 2 tablespoons of sugar, and a half teaspoon of cinnamon. After I put it in a tin on top of the fridge to rise, I went down to the shop to get some ingredients for a cake. I waited 4 hours before I put the bread and a tea cake into a hot (190C) oven. The cake should have been baked at a cooler temperature. The bread could have been baked in a hotter oven. When I took the cake out, I slided a knife around the edge. I smacked it upside-down ways on the bench and the bottom of the cake held onto the tin. I realized I could have overlooked the bit where the recipe says to use baking paper. Also the bread had not quite doubled in size prior to putting it in the oven but I put it in anyways, knowing would grow while baking. And this is what it did. If I had given the bread longer to rise it wouldn't have risen so askew.
