How to make street fruit puree?

The method for making street cakes is as follows:

1. Soak glutinous rice and japonica rice in clear water for 2 hours, wash them, take them out, add 2500 grams of water and grind them into rice slurry. Put the white sesame seeds into the pot and fry them over low heat. Pour beeswax into hot oil to dissolve it. ?

2. Add water to the pot and bring to a boil. Put it in a steamer, spread clean gauze, pour in rice paste, steam for about 150 minutes, wrap it in cloth, take it out and put it in a porcelain basin. Grab a corner of the cloth with one hand, and press it with the other hand, and knead it continuously until the cooked pulp becomes sticky dough, pour it on a wooden board evenly covered with beeswax, and then evenly spread beeswax on the skin of the cooked dough. ?

3. Wipe the beeswax evenly on your hands, take the cooked dough 1/5, rub it into round strips, pick it into 20 small portions, wrap it with eight fruit fillings, pinch it tightly at the end, dip it in white sesame seeds, and flatten it slightly (the remaining 4 portions are completed by this method).
