In a medium bowl, lightly smash the raspberries with the back of a fork.

Add the port, and mix to combine.

Arrange the graham crackers, marshmallows, and chocolate bars on a serving platter.

Toast marshmallows over an open flame.

Assemble each S’more by topping a graham cracker half with a square of dark chocolate and a spoonful of the smashed raspberries.

Layer on the toasted marshmallow and top with remaining graham cracker.
