goya, but not the painter

I always enjoy the vegetable area of supermarkets of a foreigner country and try to find a fruit of a vegetable that I don't know.
Well...the shops in Khovd didn't propose a wide range of choice (carot, onions, potatoes and cabbage). But in Japan, I was constantly discovering something new and sometime pretty strange. Here is a goya, a kind of cucumber, very bitter, found in the fantastic garden of Kozy's parents.
