Build the ingredients in a snifter. Add crushed ice and stir briefly to mix and chill. Insert a sturdy straw (preferably metal) into the glass. Vigorously shake a bottle of salted-cinnamon cream for 5 seconds to whip it, then slowly float 1 oz. on top of the cocktail until it reaches a 1/4-inch from the top. Add more crushed ice on top. Garnish.
Salted-Cinnamon Cream
Add all of the ingredients to a small bowl or container. Add the ground cinnamon slowly between whisking in each ingredient. Whisk together thoroughly for 30 seconds. Pour into a 375ml bottle so that there is empty space in the bottle to be able to properly whip the cream when shaking it. Keep refrigerated between uses.
Himalayan Salt Tincture
Mix 1 part extra-fine-grain Himalayan salt into 5 parts water and 5 parts vodka.
