Cashew:

In Goa cashew apple is used to make an alcoholic beverage which is called as "FENNI".

Unlike other nuts cashews can not be sold with their shells . This is Because the shell layer contains caustic resin that needs to be removed to make them edible to eat. Caustic Resin substance is related to toxic urushiol oil also found in poison ivy.

Unshelled cashews are therefore roasted, high pressure steamed and cracked to remove the shell oil, called cashew nutshell liquid (CSNL)

Whitehouse visited Persia and brought back dozens of carefully selected pistachio nut varieties to plant in the US . Pistachios trees take 7 to 10 years to mature, So Whitehouse has to wait to see if he had succeeded in growing pistachio in western soil. Only one nut survived Whitehouse had chosen a nut from the orchard belonging to the Agah family in Iran.
