Yángméi (杨梅) – it’s Chinese name for subtropical tree called Myrica rubra (or more commonly translated as Red Bayberry, Yumberry or Waxberry – from that alone you can guess that it’s definitely a berry of some sort ;o). It’s grown mostly in South-Eastern Asia. It’s a small evergreen tree growing from 5-10m high. It has round, crimson fruit of a size compared to the one of strawberry. There is a single seed inside.
How does it taste? In my opinion similar to blackberries. It’s a little bit sourer though. Is it tasty? I’ve eaten better things in my life but it’s definitely worth trying to eat something new. Try yourself! It’s cheap (usually 10-20 RMB/kg).
