Step 1: Put taro in a soft plastic bag, put it in water, then seal the plastic bag and rub it outside the plastic bag with your hands, until the taro is clean by washing it with your hands.
step 2: put the clean taro into the rice cooker.
step 3: don't boil taro with too much water, just let the water pass the taro.
Step 4: Cook in a rice cooker for 25-3 minutes.
note: to judge whether taro is ripe, you can stick it with chopsticks before taking it out of the pot. If you can easily stick it thoroughly, it will prove that it is ripe and edible.
