Step 1: The Materials
Fire (more importantly, the coals)
A nice long stick
Step 2: The Technique
The best way roast the marshmallow is in the smoldering coals, which is actually hotter than the flame at times, but no flame to catch your treat on fire. This will take longer to cook, but is definitely worth it.
You want to watch your main ingredient carefully, slowly rotating it until you reach a nice golden brown color. Take away every now and then so you don't burn it! This insures a perfect smore.
