Because the water didn't boil, the electric baking pan didn't stick. If you want to use an electric iron pot to stew meat and paste cakes, you must first boil the water and wait until the pot is hot before pasting cakes. Stick hard, like throwing. There is a two-part allegorical saying: Sticking cakes in a cold pot-sinking to the bottom. In other words, the pot is not hot and the cake is not sticky.
