Combine the heavy cream, milk, sugar and salt in a medium saucepan set over med/low heat. Heat until the sugar is dissolved, about 5 mins.
Whisk the egg yolks together in a medium bowl. Gradually temper in the hot cream mixture, adding one ladleful of cream to the eggs while whisking continuously. Repeat, until you use half of the hot cream mixture. Carefully pour the yolks and cream mixture back into the pot with the rest of the cream.
Turn the heat to low and continue to cook the mixture until it thickens and coats the back of a wooden spoon. (If you drag your finger across the coated spoon, the trail should remain.) Make sure you stir frequently and don't turn the heat up too high as the eggs could scramble.
Once the mixture has thickened, strain using a fine mesh strainer, into a clean bowl.
In a separate microwave safe-bowl, combine the marshmallow fluff with the water and heat for 20-30 seconds in the microwave. Mix well and then whisk into the ice cream base.
Cover the ice cream base with plastic wrap (press the plastic to the surface of the ice cream) and place in the refrigerator to chill at least 4 hours or overnight.
Place the marshmallows on a baking sheet lined with non-stick foil. Use a kitchen torch to brown the marshmallows or alternatively, brown them in the broiler. Keep careful watch, as they do burn quickly. Set aside.
Heat the remaining cream in a small saucepan until hot but not boiling. Place the chocolate chips in a small bowl and pour the hot cream over the top. Allow to sit for 5 mins then whisk until completely blended.
Chill ganache until almost set, but still pourable.
Once the ice cream has chilled, freeze it in your ice cream maker according to the manufacture instructions.
Working quickly, add half of the ice cream to a large pan or baking dish. Layer crumbled graham crackers, toasted marshmallows and chocolate glance over the top. Add the remaining ice cream and layer again with grahams, chocolate and marshmallows.
Freeze for at least an hour before serving.
