put the prepared wormwood cake in a steamer, steam it for 2 minutes, then turn off the heat and take it out. In this way, the glutinous rice flour dough is sticky and does not come loose. Be careful that you can't do it without making paste. Be sure to oil it, or it will stick to the leaves. Pay attention to keep the pot cover moving horizontally when taking out the pot, avoid vibration, and try not to drop the water vapor on the pot cover on the wormwood cake. Otherwise, it will affect the aesthetics of printing.
