I love Tiramisu any way I can get it. This is awesome.
Opening a hot oven door too early causes cheesecakes to deflate and crack from sudden temperature drops. Successful baking relies on controlling ambient heat and managing moisture levels through a water bath placed on the lower rack. This steam moderates surface drying while the interior sets.
Remove the pan from the oven when the outer two inches feel firm, but the center still jiggles slightly when nudged. Residual heat finishes the cooking process during the initial cooling phase. Turning off the heat while leaving the door ajar allows the internal temperature to drop gradually over twenty minutes. Rapid chilling traps steam inside the structure and yields a watery consistency. Refrigerating the dessert for at least three hours stabilizes the starches and fats completely.
