The sweet stuff isn’t just for children at Aroa Fine Chocolate. At the South End chocolaterie/patisserie, you will find chocolates seasoned with basil, tea, stout, liqueur, port, ginger and chilies. Consider them NC-17-rated indulgences for grownup trick-or-treaters.

While the ancient Aztecs used to consume melted chocolate mixed with chilies, Aroa executive pastry chef Tim Brown says the other unusual flavorings are modern-day inventions.
