Wash the barley and soak for 4 hours or more
Even with the soaked rice water, add the appropriate amount of water into the pressure cooker. The amount of water is larger than the amount of thick porridge. The electric pressure cooker is pressed for 30 minutes. It is estimated that the gas is 10 minutes. If the casserole is stewed, it takes 60 minutes.
After the glutinous rice water is cool, add lemon juice, honey, and mix well.
