1. Sift all the powders and mix them with sugar

2. Slowly pour in the hot water, mixing with chopsticks while pouring until the flour can be formed into a ball

3. Add the oil in 2 batches, and knead the dough until it forms a smooth ball

4. Divide the dough into 30 grams of small pieces, and roll them out with a rolling pin to form a round shape

5.

5. Wrap 15 grams of filling (lotus seed paste, bean paste, sesame seed paste, etc. can be as long as you like), I used the bean paste filling this time and the leftover sesame peanut filling for the sweet message

6. Wrap the filled dough and roll it into a ball shape

7. The first thing you need to do is to put the cake in the mold and knock it on the plate a few times, then pull out the cake

9. Boil water in the steamer and put a little oil on the steamer rack, then put the cake in the steamer and steam it on high heat for 10 minutes, then turn off the heat and let it cool down a little bit (just a little bit, not completely), and then take out the crystal cake from the steamer rack. Eat it while it's hot. If you eat it the next day, heat it up and eat it again
