½ cup half and half, or nondairy milk
1 cup chocolate chips
1-2 tablespoons bourbon, peppermint schnapps or Kahlua (optional)
1 package graham crackers
Heat milk in a heavy-bottomed sauce pot (on top of wood stove or any hot surface) until steam starts to rise. Add chocolate chips and stir until melted. Stir in liquor, if using. Keeping fondue warm, use long skewers, chopsticks or fondue forks to dip marshmallows in chocolate and place on graham crackers to eat.
If using a slow cooker, simply combine milk and chocolate chips in the pot and set to high for half an hour. Stir to combine, add alcohol, if using, and proceed with the recipe.
