It doesn't matter how old you are - there's still a little kid inside you who just loves roasting marshmallows over a campfire. However, if a campfire is a impractical for your next dinner party, try this simple trick: use your fondue set for tableside s'mores. [Caution: locate your nearest fire extinguisher before attempting, and don't serve alongside that bottle of 90-proof brandy.]
To make your s'mores a bit classier, try using premium chocolate (sorry Hershey's, it's not me, it's you). I prefer Seattle-based Theo Chocolate's Coconut Curry and Fig, Fennel & Almond, though there are hundreds of exotic flavors out there that will easily earn you your Open Flame Artisan Pastry Making merit badge.
