I previously featured the Duku Langsat a seasonal tropical fruit found in South East Asia. I mentioned that it was a hybrid fruit of the Duku and the Langsat. Well, around September every year is always Duku season and I managed to get a picture before it was all polished off by my family! 
The Duku is a tropical fruit also found predominantly in the South East Asian region and in abundance in Malaysia. However, the fruit does not travel well so you don’t find it exported and even in the big city its not easy to find fresh Duku fruits.
The Duku has a hard outer skin unlike the Duku Langsat. The skin is a golden ochre shade and is thick. When opened, the opaque flesh covered seeds are revealed. This is the edible part. The size varies from that of a ping pong ball to a golf ball.
The taste is sweet-sour and if you aren’t careful, can be teeth-achingly sour. It is more flavoursome than the Duku Langsat so I prefer it. The way to choose a sweet Duku fruit is to lightly press the part near the tip of the fruit. If it gives easily, its likely to be sweet and if its hard to open, its likely to be sour. Also, it is said that a fruit with a tapered tip instead of a fully round fruit is more likely to be sweet.
A good fruit will be sweet with thick flesh. The Duku fruit is sold loose by weight and is commonly found outside of the city in the smaller towns.
A fresh duku fruit will be lightly golden in colour with few blemishes and dark spots and the tip will be pale in colour. If it has a lot of dark spots or blemishes or you see liquid at the tip of the fruit, its turning bad which happens within a day or two of harvest.
If you have the chance, pick up a Duku fruit today!

Oooo I just had this last week, I like. I think I may have mistakenly called it chiku all along… now I learn a new (proper) name for this tropical delight
@noobcook: A Ciku is quite a different fruit
I’ll find some ciku and write about them soon!
Goodness gracious me, how on earth did you get hold of dukus? I haven’t seen them in donkey years. See mostly duku langsat these days. Not fond of duku at all, I always seem to end up with the sour ones.
@Cheesey Poo: I get my regular supply from home!
I love them and can eat them by the kilos 
I just saw some guy selling these by the airport yesterday. I was surprised they have it too here. I guess same things grow at all over southeast asia.
I don’t really dig it either. They are so small and I always get the bitter seed. But I am happy for you! Duku season!
So tantalizing! I miss all the local fruits!
This is very similar to our lanzones here in the Philippines. I especially love the flesh but the bitter pit gets in the way. The smaller ones don’t have the seeds developed yet that’s why they’re the best ones to eat.
back in the Philippines we call this “lanzones”. i miss this place.
the think is my name is Duku and i live in Romania
