"Mom, that smell is making me want to throw up," is the unintended reaction Rebecca Koffman of the Washington Post got when she tried to feed her kids black treacle toffee as a Halloween treat. She gives us the story behind this beloved British treat, which is traditionally eaten on Guy Fawkes Night, along with a recipe so you can make it at home.

Despite her kids' reactions of horror, I'm now curious to try this shiny, black candy with a rich, smoky flavor. Buy it online or head to your nearest purveyor of British goods.
