Create a horse’s neck garnish (long peel of citrus): run a vegetable peeler once around the entire circumference of the pomelo, creating a large spiral twist. Place the twist inside of a highball glass so that it curls upwards inside of the glass. Fill the glass with ice – this will hold the horse’s neck in place.
In the bottom of a mixing glass, add the honey syrup and jalapeño slice, then muddle.
Add the Hangar 1 Straight Vodka, pomelo juice, vermouth, and elderflower liqueur. Fill with ice and shake for approximately 10 seconds.
Strain into the prepped highball glass, top with soda water, and serve!
