The chocolate bars made by Green and Black’s are organic and very good; they’re available at Target stores and Whole Foods. Especially nice is their white chocolate. You needn’t be a white chocolate lover to enjoy it.
Their Maya Gold bar is flavored with orange; there’s also a mint chocolate, a 70% dark chocolate, and more–twelve flavors, in all. The holy grail of Green and Black’s bars is the butterscotch flavor, which isn’t available in the States. You can find them in the UK and Toronto.
