Special equipment: eighteen 12-inch bamboo skewers, soaked in water for 30 minutes; 6 small ramekins
Scald the cream by warming it in a small saucepot over medium heat until bubbles form around the edges and steam rises from the surface.
Place the chocolate in a large bowl. Pour the hot cream over the chocolate and let sit for 3 minutes. Stir until well mixed, then whisk in the sour cream. Place the ganache into 6 small ramekins.
Pulse the graham crackers and almonds in a food processor until well chopped (or chop finely by hand). Divide among the ramekins.
Thread the strawberries, chopped fruit, and marshmallows onto skewers. Rotate the skewers over a campfire or open flame until the marshmallows are toasted.
Dip the skewers into the chocolate fondue and enjoy!
