S'mores
Toasted marshmallow and a square of chocolate pressed between two biscuits, and a rare case of a dish whose entire technique is a heat-transfer problem: the marshmallow has to melt the chocolate.
What is disputed
A recipe for "Some More" appears in a Girl Scouts handbook published in 1927, which is the earliest well-attested printed source and is routinely reported as the invention. It is safer to read it as the earliest documentation: the components were all commercially available before then, and the combination is obvious enough that a printed recipe is more likely to be recording a practice than originating one.
This is a current practice
Made constantly, around fires and increasingly indoors, and now a flavour category of its own — s'mores appears as a description on ice creams, coffees, cereals and chocolate bars, which is unusual for a campfire preparation.
A s'more is a hot toasted marshmallow and a piece of chocolate sandwiched between two graham crackers. The construction is almost entirely about heat. The chocolate is not heated directly; it is melted by contact with the marshmallow, which comes off the fire at well above the temperature chocolate needs and holds that heat because it is a sugar foam with a great deal of thermal mass for its size.
That is why the timing matters and why an under-toasted marshmallow gives a disappointing result: the chocolate stays solid, and a s'more with unmelted chocolate is three ingredients rather than one thing.

Why milk chocolate is the right answer for once
This catalogue is generally sceptical of the assumption that darker is better, and the s'more is a case where the sceptical position points the other way round entirely.
A s'more is already extremely sweet — a sugar foam and a sweet biscuit — and the intuition is that a dark chocolate would balance it. In practice a high-percentage dark chocolate has two problems here. It contains less cocoa butter proportionally than people expect and more cocoa solids, so it melts less readily against the marshmallow and can stay grainy. And its bitterness and astringency arrive against a marshmallow that has no acidity or salt to mediate them, so the result reads as harsh rather than as balanced.
A milk chocolate melts faster, at a lower temperature, and its own milk and sugar sit comfortably with the marshmallow. If you want more chocolate character, a dark milk chocolate in the 45 to 55% range is the useful move — it melts like a milk chocolate and tastes considerably more of cocoa.

- Why chocolate meltsThe melt curve the whole construction depends on — cocoa butter goes liquid just below body temperature, and a hot marshmallow is far past that.
- Milk chocolateThe chocolate the dish is built around, and why a high-percentage dark bar is the wrong choice here.
