Can not be cooked together, sago will be cooked rotten. You should first cook sago, cooked and cooled for use, and then cook sweet potato, cooked and put milk sago a little bit of cooking on the OK. \x0d\ steps are as follows:\x0d\1, sweet potatoes should be cut but do not cut too small, because cut too small is easy to melt away. Soak the sago in cool water for 5 minutes, stir gently and pour off the water and set aside. \x0d\2, pot of boiling water put sago, cook for about 5 minutes, become transparent, turn off the fire, if the middle of a little white, cover the pot and simmer for 3 minutes, the white point will be gone, and then pour out the excess water, sago poured into another clean container, cool water, wait 1 minute to pour out the water and then put cool water again. (This way the sago is more flexible!) \x0d\3, pot of water to put sweet potatoes to cook until sweet potatoes into 80% soft put sugar, sugar almost melted put sago, boiled put milk, stirring until slightly rolled can turn off the fire, chilled better to drink. \x0d\ Note: Remember to stir after putting milk, do not cook to fully open, because the protein will denature Oh, cook all fully open milk will be solidified very ugly.
