I had to google what poi is.
"poi, starchy Polynesian food paste made from the taro root. In Samoa and other Pacific islands, poi is a thick paste of pounded bananas or pineapples mixed with coconut cream; the word originally denoted the action of pounding the food to a pulp"
Bananas and pineapples and coconut actually doesn't sound that bad together! But with pickled beetroot?? That's an odd combo...
