Negroni Dolce Cocktail
The Negroni cocktail is a drink that the palate has to learn to like. Adding simple syrup to the drink buffers some of the bitterness. Some folks enjoy adding a couple of ounces of club soda as well.
Angostura bitters can be added as well for a different flavor. This drink should not be shaken.
Another option for the garnish is to carefully light a match and hold over the glass while squeezing the peel into the drink. Blow out the flame, discard match, and drop peel into the drink.
