The character 双 in the dish name 炒双冬。 How did the character 双 in the dish name 炒双冬 come to mean "bamboo shoots"? Isn't 双 just a character meaning "pair"? Also, why 冬(winter)?
I think it's 炒双冬. 双 here means two. One 冬 is 冬菇, also known as 香菇, a kind of mushroom, lentinus edodes. The other 冬 refers to 冬笋, bamboo shoots.
