Gooey melted marshmallow and melty chocolate sandwiched between graham crackers. Traditionally you skewer the marshmallow on a stick and cook it in a campfire. Indoors, s'mores are easily made in a microwave. Though, with microwaving, you don't really get that blackened-marshmallow taste (the trick is to get it to catch on fire). They actually sell indoor s'mores cooking kits, which are almost like little bunsen burners, just for roasting marshmallows. I find that ridiculous. A candle works just fine. All you really need is a FLAME. Hell, if you're determined enough, you can even get a marshmallow to catch fire on an electric stove.
