I thought a Marshmallow test would be about who can toast one a perfect brown color vs. those who turn it into a flaming charcoal mess.
It’s the same test actually: Are you disciplined and capable enough to hold marshmallow exactly far way from the fire for a longer time, rotating it it slowly and steady enough to get the golden brown color? Or you try to get too close to try to cook it quickly ? And so burn it with lots of neat flames and smoke?
