Daisy

A Daisy is a Sour that's sweetened with a little orange liqueur, strained and then fizzed. (It's the orange liqueur that makes a Daisy a Daisy and not a Fizz and distinguishes the daisy from other sour cocktails.) That makes a traditional Daisy a traditional long drink made with a base spirit, lemon juice, sugar and orange liqueur or grenadine and topped off with fizzy water. The most common daisy cocktail is the Brandy Daisy, followed by the Whiskey Daisy. If you make your Daisy with tequila and lime (instead of lemon) you have a margarita.

The Brandy Daisy is a cocktail which first gained popularity in the late 19th century. One of the earliest known recipes was published in 1876 in the second edition of Jerry Thomas's The Bartenders Guide or How To Mix Drinks: The Bon-Vivants Companion:

3 or 4 dashes gum syrup
2 or 3 dashes of Curaçao liqueur
The juice of half a small lemon
1 small wine-glass of brandy
2 dashes of Jamaica rum

Fill glass one-third full of shaved ice. Shake well, strain into a large cocktail glass, and fill up with Seltzer water from a syphon.

A later recipe, published in 1941 in Old Mr Boston's De Luxe Official Bartender's Book includes the following instructions:

2 oz California brandy
juice of ½ lemon
1 tsp raspberry syrup or grenadine
½ tsp powdered sugar
fill cracked ice

Shake well with cracked ice and strain into stein or 8 oz. metal cup. Add cube of ice and decorate with fruit.
