In a bowl whisk the heavy cream, powdered sugar, and vanilla until stiff peaks form. (Can use an electric mixer if desired). Then refrigerate.
In a large mixing bowl, whisk together the flour and the egg. Gradually add in the milk and water, stirring to combine. Add the salt and butter; beat until smooth.Heat a lightly greased griddle or frying pan with nonstick spray over medium high heat. Pour or scoop the batter onto the pan, using approximately 1/4 cup for each crepe. Tilt the pan with a circular motion so that the batter coats the surface evenly.Cook the crepe for about 2 minutes, until the bottom is light brown. Loosen with a spatula, turn and cook the other side. Repeat for remaining crepes.
Spread the jelly and nuts in the crêpe and roll up. Top with whipped cream. Serve with orange.
