This soup has become one of my favourite comfort soups. When the coconut and sweet potato come together, it becomes a buttery soup. It's hard to explain the loveliness of the flavour, so really you must taste it and find out for yourself!
While its immensely tempting to rest every single bed under a thick layer of mulch, cardboard or black plastic and head north to the sunnier states for winter, I try to rest one bed and plant lovely greens to enjoy for winter suppers.
While I have grown potato onions and spring onions widely at times, the Negi onion is the one that remains outside my kitchen door and never dies off. Happily this year, they self-propagated (perhaps from the east winds swirling around the place), so now I have three pots outside the kitchen door.
