Chicken egg fruit

I don't even know what it is in English.  Hahahah.  It is a seasonal item.  And the person who let me try it bought it in Yuen Long, which is faaaaaaaar away.  The texture is very much like hard boiled egg yolk...hence the name "chicken egg" fruit.  It's not juicy.  Dense.  Not too sweet.  I'm indifferent.  Glad I got to try something new though.
