I’m writing this from a desk covered in chocolate things. Cacao things, to be exact. Cacao is as ubiquitous as coconut water these days, which is wonderful, but also often confusing. For example, is the cocoa butter in my body cream the same stuff that’s in chocolate? (Yes.) And, what the hell are nibs, really? Given how much of the cacao plant is beneficial, and being used, it’s worth knowing one’s way around it.
