Love it! my first Tatin and it came out perfect! Even though I forgot to pre heat the oven. I stopped cooking the sugar at 310* poured it over the plums and it became rock hard. I wasn't sure if this would work. Once the oven heated I poured on the cake batter and cooked it for 45 minutes. Let it rest for 15 minutes... inverted beautifully. We will be making this again.
