@Georgesplane- Poi is really easy to make. It is very similar to making mashed potatoes. To make the poi, you will need some good Hawaiian taro. Dasheen is Japanese taro and is not good for making poi. Dasheen will be bland and tasteless.
Peel and cube the taro in a stockpot until it can be fork pierced. Once drained, place the taro in a food processor (or you can hand pound it with a mortar and pestle if you want to do it the traditional way). Add just enough water to the taro to create the consistency that you are looking for. One-finger poi is thick while three-finger poi is thin.
Once you have made your poi, let it sit on the counter covered in a little sprinkle of water and a clean damp towel for three days. This will turn poi slightly sour, giving it its distinct Hawaiian taste. Enjoy!
