This is the original 1927 recipe for “Some More” as it appeared in the Girl Scouts manual, Tramping and Trailing with the Girl Scouts.
8 sticks (for toasting the marshmallows)
16 graham crackers
8 bars plain chocolate (any of the good plain brands, broken in two)
Toast two marshmallows over the coals to a crisp gooey state and then put them inside a graham cracker and chocolate bar sandwich. The heat of the marshmallow between the halves of chocolate bar will melt the chocolate a bit. Though it tastes like “some more” one is really enough.
