Pour all the ingredients into a cocktail mixer.
Shake well until condensation appears on the outside of the shaker.
Make a salted sugar rim on the glass by wiping the edge of each glass with lemon juice and dunking it in a mix of sugar and salt (2tsp sugar to 1/2 tsp of salt)
Leave for 2 minutes to let the ice melt to take the edge off the spirits and then strain into a glass.
Garnish with a few saffron threads and serve.
