When I was a kid, these things:
In school Now and Laters and Jolly Ranchers were king.
Hickory Farms used to sell cocktail flavored hard candies that were awesome. They're probably outlawed now.
As an adult I lean towards chocolate. I'm on a diet so this year I didn't go and stock up on discounted Halloween candy for the first time in ages. Generally I'd go with a big bag of bit sized Peanut butter cups, and one bag of mixed mini candy bars. Hershey's or Nestles, either way.
Insofar as alltime favorite candy bars, 100 Grand bar, Payday, and probably Score. There's certainly nothing wrong with a Snickers, either.
Generally I prefer milk chocolate to dark, but dark+orange is a winning combination.
Not a truffle guy at all, but there's
a place down here that makes bonbons with the artistry of DaVinci, and the perfect design you'd expect from JPL. Every bite has the perfect amount of crispy, chewy, fruity, chocolaty, or crunchy that the particular confection calls for. It's basically a $75 Witman's sampler.
