A bon bon is the dessert that some husband’s accuse their spouses of eating all day, while they’re at work. You know how it goes. ‘What did you do all day? Sit around and eat bon bons?’ Just teasing you. Husband’s don’t really say that. A bon bon is a vanilla ice cream, wrapped up in chocolate, if you buy it in the U.S. It will also melt if not eaten quickly. However, in Europe, they are butter cream on the inside, covered with chocolate on the outside, so they don’t melt.
