Some folks use a twist of citrus in their Manhattans and, yes, if you look around, there are a good number of people who “go rogue” with the cocktail and I recently read an article about some hardy soul that used 4 parts rye to 1 part vermouth, and even used non-rye in his. (I prefer rye.) But I am interested in trying these with half sweet vermouth, and half dry, which is called a Perfect Manhattan. I guess another trip to the liquor store is in order. Cheers!
