Think of the golden claws of Buddha's hand, the lime-green pearls that burst from finger limes, and the jet-black skins of wild berries that look like something a witch might toss into her brew.

Beneath their eerie colors and unusual textures, wild and exotic fruits remind us that curiosity, both sensory and scientific, is one of the best things we can feed our brains.
