When steaming purple potato cakes, if you put them in a pot, brush oil at the bottom of the pot to avoid sticking to the pot. In addition to steaming in a pot, you can also spread oil paper under the steamer and put it on it, so that the purple potato cake will not stick to the pot.
Don't open the lid in a hurry after steaming. Let it stew in the pot for another 5 minutes, wait until the temperature drops slightly and there is no steam, then remove the lid, so that the shape of the cake will not be destroyed. If water vapor enters, it will expand with heat and contract with cold, and the appearance of the cake will collapse.
