Why? It turns out that the cashew shell is toxic. However, that raised the question of what a cashew looks like in its shell. Again, we had no idea. When we found out, we knew more people should see it. Weird looking, isn't it [follow link for photo]? And caustic, too!
Cashews, like many of the culinary nuts listed above, are not true nuts in the botanical sense. True nuts develop a hard wall around the seed (e.g. hazelnuts). Cashews instead have a lining around the seed that is filled with a nasty fluid.
