The perfect s'more is practically burned and a little salty

The campfire s'more is a gooey mess: saccharine, certainly, but also sentimental, stuffed with childhood memories.

"When you get older, you still love them," said Kena Peay, a cook who shares her hiking and camping recipes on social media. "But then you're like, 'Uh, this kinda could be improved.' "

Beloved for its simplicity, a s'more is best known as a roasted marshmallow and a piece of bar chocolate sandwiched between graham crackers. But, really, the perfect campfire s'more is one you enjoy. For some, that can be a roasted Peep with a Reese's cup tucked into two gingersnap cookies. The potential for customization is endless.

The s'more's origins are as hard to pin down as its oozing center. The first published recipe is often attributed to the 1927 guidebook "Tramping and Trailing With the Girl Scouts," where it appears under the name "Some More."
