I have to credit Cake Wrecks again for this link to an article by Serious Eats about the Sweets & Snacks Expo formerly the All Candy Expo. Reading the article is enough as Zemans does an awesome job giving the low down. I'm looking forward to the caramel and nut Snickers the most. I'm weirded out by chocolate covered Peeps, but the purple is appealing.
The link above is Part 1; here is Part 2 and Part 3. Part 2 features more snacky foods while Part 3 features unknowns. I'm particularly interested in the Winky. Yeah, you need to read the articles ;)
