Take a Cashew fruit in your hand. You can remove the seed/nut first then cut off the top part of the fruit where the seed was attached too.
This part of the fruit is rather astringent and should be removed if you want to avoid throat itching sensations. (just like the pineapple center)
Keep aside the raw green seed/nut nut for the roasting process and cut your edible part of the fruit into bite size pieces.
You can indulge it already at this point. Sprinkle some salt on top and keep the fruit in the sun for a short time to take out some of the fruit liquids. It gives a bit of a flavor but it's not required, in fact I just prefer to eat the fruit raw. Of course it can be processed further into other delicacies such as Chutneys and Pickles.
