Mandarins are indigenous to south east Asia, and sometimes these are given as freebies in the cafeteria where we have lunch. A closely related fruit of this kind is found in South Africa, where they are called naartjies in Afrikaans, originally from the Tamil word nartei meaning citrus.
This plump little ‘loose-rinded fruit from a spiny orange tree’ as Merriam-Webster describes it (see below), was easy to peel and delicious!
