If any old pastry chef put a marshmallow in the freezer and called it a frozen s'more, it wouldn't really register. But when Cronut sensation Dominique Ansel does, well, commence freak out. The chef dropped word of the new item in a column for Huffington Post, and apparently they quietly debuted last week (and promptly sold out). It's ice cream that's wrapped in a marshmallow shell and then charred. Well, we think people will still be lining up for the Cronut craze, but it's nice that they'll have something to cool down with when they hit the front of line.
