From the success of the Manhattan sprang other cocktails with sweet vermouth. While many of the details changed, the formula was a simple one: equal parts vermouth and spirit, something sweet, and bitters. The Martinez was the next big hit that came out of this formula. Gin shows up again in #100DaysOfCocktails.
#100DaysOfCocktails - Day 10 - Gin Daisy
The Daisy is a class of cocktail all its own. It is very similar to a Fix, with the only difference being the sweetening syrup you use. Professor Jerry Thomas used orange liqueur and gum syrup. Later recipes call for grenadine or raspberry syrup. #100DaysOfCocktails used the grenadine, and the flavor is outstanding.
