Take a proper amount of soybeans and put them in a basin. Take soybeans according to your own consumption.
Then pour a proper amount of water into the basin, not more than soybeans.
The next step is to wait for the soybeans to be fully soaked in water. At least when necessary, then take out the clean towel prepared in advance and put it in the leaky frame.
Then, pour the soaked soybeans on the towel, and then use a bucket to filter the water.
Then take out the prepared plastic bag and cover it on the bean sprouts.
Finally, give me the time to wait for three days. In the middle, water the beans twice. Remember to use the above water to soak the beans. They will be ready in three days. Is it very simple and magical.
