Cacao nibs are showing up all over the place these days. My Fare Foodie puts them to good use in a simple microwave version of caramel corn.Cacao nibs are all-natural bits of ground cocoa beans that have a nice crunch factor, a major amount of antioxidants, and a subtle chocolate flavor. How about we nibble on these little nibs in a batch of homemade caramel corn? Caramel corn can be kind of daunting since candy thermometers, rapid boiling, and extended baking times are typically involved. For this recipe, though, everything is made in the good ole microwave.
