March to May is the season for cashew juice or niro as it is called locally. we have left our house and garden in India but i have some photos of fresh squeezed cashew juice that i made there in March.
but when ripe the red accessory fruit, often called a cashew apple is full of juice. it is small and green while the drupe develops then within days swells up and turns red or yellow. if not picked within a day it drops from the tree and quickly deteriorates. the juice is exceptionally astringent and both somewhat sweet and sour, vaguely reminiscent of grapefruit juice but much less sour. it can be very tasty but the fruits should be picked in the morning before the sun is warm because in the heat they develop a toxin that can irritate your throat
i must admit that a fair amount of effort goes into making the juice this way. when out picking each morning in season if i find a perfect fruit or two i often just remove the cashew and put that end of the apple in my mouth. holding the other end i bite and suck the juice. it's much easier and instantly satisfying but not something everyone can appreciate
