All I wanted was to combine some of my favorite ingredients. I personally have not much experience in cocktail making. So in the off chance that this already exists then I am sorry.
I also like this combination without the ice in the glass.
Measure all the liquids into the shaker
Add the egg
Dry shake first for a few seconds
Add ice and shake again for 12 seconds
Fill the glass with ice.
Strain the cocktail in the glass
Add some chocolate shaving for decoration.
