Preheat the oven to 350 degrees F.
Mix together the marshmallow creme and marmalade with a rubber spatula in a medium bowl. Set aside.
Spread the almonds and pistachios on a rimmed baking sheet. Toast in the oven just until fragrant, about 5 minutes. Add the warm nuts and salt to the bowl with the marshmallow creme and fold everything together. Divide the mixture evenly among 8 serving dishes and cool to room temperature. Grate the chocolate over the top just before serving.
