The Cashew is the only fruit which it's own seed was in the outside, I didn't know we have a tree of it until it bears it first batch of it's fruits. We are too much excited for the first harvest and it's my first time to see the fruit in person as well to experienced to eat the fruit. I usually eat the nuts. The fruit taste!? It's hard to explain, it is somewhat familiar in taste of guava and pineapple in combination, taste like also of  4 season juice drink. My kids didn't like the taste at first just like me they are curious of the taste of the fruit. I also try to open the seed, it's very hard, it needs a lot of effort and be careful on the resin or the gummy sap because it has a hot but not spicy and itchy sensation to your mouth (it can burned your lips/mouth and skin) when you try to eat it in improper way, it should be prepared with care and by removing the sap by roasting and  cracking it by the professional or knowledgeable persons. The result the fruits goes to our pets dogs and chickens. And roasting of the seeds is done in closed indoors and away from chickens, the smell of the smoke of it can kill dozens of chickens, I don't know why but the myth was real and tested to be true.
