Fruit – Duku

Langsat and duku.  These are related (different groups of cultivars of the same species), and vary slightly in appearance and taste (though not so much that I would be able to tell you what the differences are).  These were labeled as “dukong” which is supposed to be a cross between langsat and duku.  Similar to a lychee, there is a peelable thin outer skin which contains the inner tender flesh.  The flesh divides into segments (like a mangosteen) and some larger segments contain a single seed.  The fleshy segments are very juicy, and have a flavor like a sweet, mild grapefruit (with a tartness to it instead of the bitterness a grapefruit would have).
