I’ve seen candy in the US that looks like lumps of coal (it’s a licorice-flavored hard candy, fairly shiny). A friend of mine mentioned this sort of thing being a traditional treat in Spain at Christmastime, but she couldn’t find the official Spanish name for the stuff. Some googling suggests it’s either “carbón de azúcar” or “Carbon de Reyes”, but each term only showed up once or twice.
Can anyone tell me the correct term? Nava, are you out there?
