Combine all ingredients into a mixing glass, add 75% ice and stir 10-15 seconds. Single strain into a coupe.
I took out the vodka entirely, and chose an American gin for its more subdued botanical strength. The anejo tequila was chosen for its golden color and softer background flavors of oak and vanilla. The demerara syrup also adds to the color and embellishes the sweet background notes. Orange bitters to give a roundness of citrus. I love this drink and have sold a few in the past, not bad for a drink of gin and tequila.
The original shot was called a "tejeuve", or the Spanish abbreviation for TGV, Tequila, Gin, Vodka. It was a double shot which was comprised of the three spirits, and chilled.
