Add the taro, sugar, salt, and water to your rice cooker. Start a "quick cook" (if you have a multi-function rice cooker) or the normal cycle (if you have a standard rice cooker). If your rice cooker has a timer, add the sago 13 minutes before the cooking cycle ends. If it doesn’t, add the sago 15 minutes after starting the cycle. The total cook time should be about 25-30 minutes.
⅓ cup granulated sugar, ⅛ teaspoon salt, 3.5 cups water, 2.5 tablespoon sago
