Marshmallow
Marshmallows were a Terran confection consisting mostly of sugar and egg whites. 

They were used in many desserts, including Rocky Road ice cream and smores where it is toasted and sandwiched between chocolate and graham crackers. When attempting to describe them to Liana in 2151,  wasn't sure exactly how to define them. He also didn't believe they factored into the flavor's name. ()

Traditionally, camping out includes toasting marshmallows over a campfire. After researching the 's database in 2287, Spock brought a marshmallow (or "marshmelon", as he called it) dispenser along for his shore leave in Yosemite National Park with Leonard McCoy and James T. Kirk. After consuming a marshmallow, it is traditional to then engage in a sing-along. Later, Kirk attributed their apparent weightiness while attempting to hitch a ride on a levitation boots-wearing Spock in the Enterprise-A's turboshaft to "all those marshmelons." ()

In 2380, Sam Rutherford said that the  smelled like "toasting marshmallows on a cool night" to him, at which D'Vana Tendi promptly alerted him to a nearby plasma fire. ()
