Ingredients for lemon drop cocktails vary slightly depending on the recipe, but vodka and lemon juice are always used in some form. Sugar, simple syrup and triple sec are typical additions.
Lemon drop cocktails are sweet-and-sour drinks that many people consume with dessert, and are usually served in martini glasses. To make a bare-bones lemon drop cocktail, the preparer combines lemon juice and vodka over ice in a cocktail shaker, and then strains the mixture into a glass. Other recipes add sugar or simple syrup with the vodka and lemon juice, and triple sec or other orange liqueurs to enhance the citrus flavor. Many people also choose to coat the rim of the glass with sugar and garnish the drink with a thin lemon slice.
A lemon drop recipe on Liquor.com calls for 2 ounces of vodka, 1 ounce of simply syrup, 1 ounce of fresh lemon juice, and 1/2 ounce of triple sec, as well as a glass with a sugar-coated rim. Ina Garten's Food Network recipe uses 2 cups of frozen vodka, 1/2 cup of lemon juice, 1/2 cup of superfine sugar and one lemon slice garnish. The recipe takes five minutes to prepare and yields six cocktails.
