M&S trials Kiyomi Marks and Spencer is trialling a new citrus variety called Kiyomi currently on sale at £1.99 for a four traypack. Grown in South Africa, it is only available in limited volumes at present and is a mandarin/orange hybrid which is late harvested and stores well. A cross between a satsuma and a Trovita orange, it was first discovered in Japan some 20 years ago where its sweet flavour, associated with a Navel, made it a success. {{FRESH PRODUCE }}
