The sticky, sweet combination of toasted marshmallow, melted chocolate, and graham crackers remains an iconic staple of outdoor gatherings across North America. While modern campers roast these ingredients over open flames on nearly every summer trip, the exact origins of who invented s'mores involve a surprising piece of organized youth history rather than an accidental campfire creation.
Official documentation credits the Girl Scouts with publishing the earliest known recipe for the treat. In the 1927 edition of Girl Scouting and Pioneer Trails, a recipe titled "Some More" appears, attributed to Loretta Scott Crew. Troop leaders and campers quickly shortened the name, transforming the phrase into the familiar contraction used today.
Evolution of the Ingredients
To understand how the treat came to be, it helps to look at the history of its three core components: the graham cracker, the marshmallow, and the chocolate bar. Each ingredient has an industrial origin completely separate from outdoor recreation.
- Graham Crackers: Developed in the mid-19th century by Sylvester Graham, these crackers originally used coarse, unbleached wheat flour intended to promote plain living and curb unhealthy appetites. Over time, bakers sweetened the recipe with honey and molasses.
- Marshmallows: Ancient Egyptians first extracted sap from the Althaea officinalis plant to make a honey-sweetened confection for royalty. Modern commercial production replaced plant sap with gelatin, corn syrup, and sugar during the late 19th and early 20th centuries.
- Chocolate Bars: Mass-produced milk chocolate bars, popularized by companies like Hershey, became widely accessible across North America by the early 1900s, making them an ideal pocket-sized sweet for campers.
The Rise of Campfire Culture
Outdoor recreation expanded rapidly during the early 20th century as automobiles became common and national parks grew in popularity. Organized groups like the Boy Scouts of America and the Girl Scouts encouraged youth to spend time in nature, teaching outdoor survival skills, campfire safety, and camp cooking.
Community cookbooks published by these organizations played a massive role in standardizing outdoor recipes. Because graham crackers, chocolate bars, and marshmallows were inexpensive, non-perishable, and easy to pack in a rucksack, they naturally became the go-to ingredients for a sweet evening snack. By the 1930s, references to the treat began appearing in various summer camp guides and regional newspapers under names like "Graham Cracker Sandwich."
Common Mistakes When Making the Treat
Even though the recipe requires only three ingredients, improper technique often leads to burnt marshmallows or unmelted chocolate.
- Using Direct Flames: Holding the marshmallow directly inside roaring flames burns the outside to a crisp while leaving the center cold and solid. Toasting over glowing hot coals provides even, gentle heat.
- Skipping Chocolate Placement: Placing the chocolate on a cold graham cracker far away from the heat source prevents it from melting. Putting the chocolate on the warm cracker immediately after adding the hot marshmallow helps soften it properly.
- Rushing the Assembly: Squeezing the sandwich too hard before the marshmallow cools can cause the molten sugar to spill out the sides. Allowing a few seconds for the layers to settle prevents sticky fingers.
Frequently Asked Questions
Who wrote down the first recipe?
Loretta Scott Crew documented the earliest official recipe in the 1927 Girl Scouting and Pioneer Trails handbook while camping with Girl Scouts in Pathfinder Camp.
Why is it called a s'more?
The name comes from a contraction of the phrase "some more," reflecting the immediate desire of campers to eat another one after finishing their first.
Can you make them indoors?
Yes, using a microwave or a kitchen broiler allows people to enjoy the treat during winter months, though traditional campfires provide a distinct smoky flavor.
What is the best chocolate to use?
Traditional milk chocolate bars melt the fastest under a hot marshmallow, though dark chocolate and filled chocolate squares offer rich flavor variations.
