This was a cocktail I did for a diabetes awareness fundraiser.
1 1/2 oz premium vodka
1/2 honey syrup (2:1)
1 dash grapefruit bitters
1 oz balsamic vinegar
First place the strawberry in the vinegar to marinate. Now combine the vodka, honey syrup, and bitters in a mixing glass, fill with ice and stir for about 15 seconds or until cold and diluted by half. Now place the marinated strawberry in a chilled cocktail glass and strain the cocktail into the glass pouring it over the strawberry. Enjoy.
