Heat the heavy cream in a small saucepan set over medium-low heat until it just comes to a boil.
Meanwhile, place the egg, sugar, salt, and chocolate chips into a blender or food processor; pulse about 8 times or until slightly blended.
Once the cream begins to bubble around the edges of the saucepan, remove from the heat. Remove the opening of the top of the blender or food processor and slowly drizzle the hot cream through the opening. Blend for about 1 minute or until smooth.
Pour into six individual serving cups - small jam or jelly jars, wine glasses, or ramekins.
Refrigerate 2 hours, or until firm, prior to serving. Serve with whipped cream.
