A Question For The Ages ...
Wouldn't you know it: The Straight Dope is the first site that popped up.
So, L.A. Dave, this post is for you. And I quote:
"Dear Straight Dope:
Everyone loves the nougat in candy bars but what exactly is it? --SubJLH187
SDSTAFF Lar replies:
Speak for yourself, SubJ. I personally find the way it sticks to my fillings vile.
According to my trusty Joy of Cooking, previous edition, nougat is a combination of sugar, corn syrup, egg whites, butter and nuts. Joy claims that France and Italy are famous for their honey-flavored nougats, then cravenly declines to give a recipe for one claiming that more careful storage of honey-containing candy is needed due to atmospheric moisture. Whatever that's supposed to mean. It's not like a plate full of homemade candy is going to sit around for a week or two.
Of course, there's no guarantee that American candy manufacturers are going to limit themselves to such wholesome ingredients. But if you want to get into a discussion of petrochemicals, you're going to have to ask someone besides me.
