The Rhubarb & Gingerbread Negroni is an autumn cocktail that was created by Emma Stokes and was first published in her book Have Yourself a Merry Little Cocktail: 80 Cheerful Tipples to Warm Up Winter. It's a simple variation of the Negroni that is made with rhubarb-flavored gin and a delectable homemade gingerbread simple syrup, along with the classic's ingredients sweet vermouth, Campari, and citrus.
Add rhubarb gin, sweet vermouth, Campari, and gingerbread syrup to a mixing glass.
Fill mixing glass with cubed ice.
Using a bar spoon, stir for 30-45 seconds until well-chilled and slightly diluted.
Add a clear ice cube to a lowball glass.
Using a julep strainer, strain into lowball glass.
Garnish with orange peel.
