First, go off into the bushes to find some nice pointed sticks. When you have found the perfect stick, impale a large marshmallow on the end and toast in the embers until soft and gooey and perhaps just a little bit singed around the edges.
We love S'mores and we want s'more!
Prepare your S'more by sandwiching a large piece of chocolate (dark or milk chocolate, it doesn't matter, it's all good) between two graham crackers, and when the marshmallow has reached just the right consistency of gooiness, plonk it on top of the chocolate and gently squeeze the graham crackers together.
The heat of the marshmallow will melt the chocolate just enough to ooze out of the middle of the S'more along with the melty marshamallow.
I think you'll agree this provides all the food groups necessary for survival in the back yard after a hearty Canada Day BBQ.
