The time for steaming and sticking the bean curd will vary due to different factors, including the size of the bean curd and the performance of the steamer. Generally speaking, the time for steaming sticky bean buns is about 15 to 20 minutes. The following is a simple step of steaming sticky bean bags:

Prepare the mixed flour of sticky rice flour and glutinous rice flour, add appropriate amount of water and stir into dough.

Divide the dough into small pieces and knead into round or oval bean bags.

Put steamer paper or steaming cloth in the steamer, and put bean bags on it, keeping a proper distance to avoid sticking together.

Heat the steamer until the water boils, and then put the steamer into the steamer.

Put the lid on and start cooking. The steaming time depends on the size of tofu and personal taste preference.

After about 15 to 20 minutes, open the lid to check whether the tofu is cooked. You can insert the bean bag with toothpicks or chopsticks. If it can be easily taken out after insertion, it means that the bean bag is cooked.

Turn off the fire, take out the steamed sticky bean bag, let it cool a little, and enjoy.

Please note that the above time is for reference only, and the actual steaming time can be adjusted according to personal taste and specific circumstances. It is suggested that appropriate adjustments should be made according to the performance of the steamer and the size of the bean bag to ensure the cooked and soft taste of the steamed bean bag.
