If you live in the U.S., chances are, your first hint of fall isn’t a russet-colored leaf landing on the sidewalk—it’s the orange-wrappered candies taking over the aisles of your local grocery and convenience stores. Forget decorative gourds: it’s officially Halloween candy season! But how did a 2,000-year-old Celtic festival marking the sun's death and the beginning of winter morph into a family-friendly sugar-fest? With the help of Heather Cox Richardson and Joanne Freeman, historians and hosts of the Vox Media Podcast Network show Now & Then, we explore the surprisingly recent introduction of trick-or-treating, and the all-American invention of Halloween as the ultimate candy-permissive, religion-free Frankenholiday. Plus, why do so many cultures around the world celebrate deathy things at this time of year—and why do so many of them involve sugar? All this, plus a rigorous candy corn tasting bravely undertaken by your indefatigable hosts!
