Food by any other name, part 2
It is a nut, served boiled. You crack the thin shell of the dark brown quarter-sized round nut, either with a nut cracker, or with your teeth as the locals do, and eat the colourless meat. It doesn't taste particularly nutty, but that is probably in part because it is boiled, not roasted. The flavour isn't particularly strong one way or another, but I was warned not to drink water immediately after eating as it would dry out my mouth.
If anyone has any ideas to solve the mystery of the Cameroonian cashews, I invite you to post and enlighten us all.
